select all that apply.
A. Interquartile range
B. Mean
C. Mean absolute deviation
D. Median
E. Mode
F.Range
==========================================================
Explanation:
The box plot, aka "box-and-whisker plot", visually represents five things. These things are:
MinimumQ1 = first quartileMedian (sometimes referred to as Q2 or second quartile)Q3 = third quartileMaximumThis list of five items is known as the five number summary.
The min is the tip of the left most whisker, assuming there aren't any small outliers. The max is the opposite side, being the tip of the right most whisker (assuming no large outliers). If there are any outliers, then they'll be shown as "island" dots on their own separated from the main box plot. The left and right edges of the box are Q1 and Q3 respectively. The median is the vertical line inside the box. The vertical line does not have to be at the midpoint of the left and right edges of the box. It simply needs to be somewhere in the box.
--------
Since the box plot lets us know the min and max, we can compute the range because
range = max - min
and we can also calculate the interquartile range (IQR) because
IQR = Q3 - Q1
--------
So to summarize so far, the five number summary is visually represented as the box plot. The range and IQR can be computed using items from the five number summary.
We cannot compute the mean because we would need the actual data set of values, rather than the summary data. The same goes for the mean absolute deviation (MAD) and the mode. Since your teacher is looking for things that cannot be determined from a box plot, we'll go for answers B, C and E.
In other words, we rule out choices A, D, and F because we can compute or determine those values from a box plot.
The nutritional content per ounce of three foods is presented in the table below. If a meal consisting of the three foods allows exactly

Food A:
OZ
Food B:
OZ
Food C:
OZ
Answer:
A = 5 ounces
B = 1 ounces
C = 4 ounces
Step-by-step explanation:
The 3 foods contain exactly 1800 calories but food A is 100 calories, food B is 500 calories and food C is 200 calories. Thus;
100A + 500B + 200C = 1800 - - - (eq 1)
The 3 meals allows exactly 75 grams of protein while A is 5 grams, B is 6 grams, C is 11 grams.
Thus;
5A + 6B + 11C = 75 - - - (eq 2)
The 3 meals allows exactly 5650 milligrams of vitamin C while A is 400 mg, B is 2050 mg and food C is 400 mg. Thus;
400A + 2050B + 400C = 5650 - -(eq 3)
Solving the 3 equations simultaneously online, we have;
A = 5 ounces
B = 1 ounces
C = 4 ounces
Food A is 5 ounces, Food B is 1 ounce, and Food C is 4 ounces and this can be determined by forming the linear equation in three variables.
Given :
The nutritional content per ounce of three foods is presented in the given table.A meal consisting of the three foods allows exactly 1800 calories, 75 grams of protein, and 5650 milligrams of vitamin C.Let the total amount of Food A be 'A', total amount of Food B be 'B', and the total amount of Food C be 'C'.
The linear equation that represents total calories in each food is:
100A + 500B + 200C = 1800
[tex]\rm A =\dfrac{ 1800 - 500B-200C}{100}[/tex]
[tex]\rm A =18 - 5B-2C[/tex] --- (1)
The linear equation that represents total protein in each food is:
5A + 6B + 11C = 75 ---- (2)
The linear equation that represents total Vitamin C in each food is:
400A + 2050B + 400C = 5650 --- (3)
Now, substitute the value of 'A' in equation (2).
[tex]\rm 5(18-5B-2C)+6B+11C=75[/tex]
Simplify the above equation.
90 - 25B - 10C + 6B + 11C = 75
C - 19B = -15
C = 19B - 15 ---- (4)
Now, substitute the value of 'C' in equation (1).
A = 18 - 5B - 2(19B - 15)
A = 18 - 5B - 38B + 30
A = 48 - 43B --- (5)
Now, substitute the value of A and C obtains in equations (4) and (5) in equation (3).
A = 5 ounces
B = 1 ounce
C = 4 ounces

Answer:

Step-by-step explanation:
As part of the Pew Internet and American Life Project, researchers conducted two surveys in late 2009. The first survey asked a random sample of 800 U.S. teens about their use of social media and the internet. A second survey posed similar questions to a random sample of 2253 U.S. adults. In these two studies, 73% of teens and 47% of adults said that they use social networking sites. Use these results to construct and interpret a 95% confidence interval for the difference between the proportion of all U.S. teens and adults who use social networking sites.
Answer:
The 95% confidence interval for the difference between the proportion of all U.S. teens and adults who use social networking sites is (0.223, 0.297). This means that we are 95% sure that the true difference of the proportion is in this interval, between 0.223 and 0.297.
Step-by-step explanation:
Before building the confidence interval we need to understand the central limit theorem and the subtraction of normal variables.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]
Subtraction between normal variables:
When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.
Sample of 800 teens. 73% said that they use social networking sites.
This means that:
[tex]p_T = 0.73, s_T = \sqrt{\frac{0.73*0.27}{800}} = 0.0157[/tex]
Sample of 2253 adults. 47% said that they use social networking sites.
This means that:
[tex]p_A = 0.47,s_A = \sqrt{\frac{0.47*0.53}{2253}} = 0.0105[/tex]
Distribution of the difference:
[tex]p = p_T - p_A = 0.73 - 0.47 = 0.26[/tex]
[tex]s = \sqrt{s_T^2+s_A^2} = \sqrt{0.0157^2+0.0105^2} = 0.019[/tex]
Confidence interval:
Is given by:
[tex]p \pm zs[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
Lower bound:
[tex]p - 1.96s = 0.26 - 1.96*0.019 = 0.223[/tex]
Upper bound:
[tex]p + 1.96s = 0.26 + 1.96*0.019 = 0.297[/tex]
The 95% confidence interval for the difference between the proportion of all U.S. teens and adults who use social networking sites is (0.223, 0.297). This means that we are 95% sure that the true difference of the proportion is in this interval, between 0.223 and 0.297.

The box plot below shows the number of students in the classes at Scott Middle School.
Identify the best measure of center and the best measure of variability of the data, and identify the values that correspond to those measures.
The best measure of center is the median.
The mean is 28.5.
The best measure of variability is the interquartile range.
The best measure of center is the mean.
The mean absolute deviation is 3.
The median is 26.
The best measure of variability is the mean absolute deviation.
The interquartile range is 5.
Answer:
The best measure of center is the median.
The best measure of variability is the interquartile range.
The median is 26.
The interquartile range is 5.
Step-by-step explanation:
A box plot displays 5 main values which are:
Minimum value
First Quartile (Q1)
Median
Third Quartile (Q3), and
Maximum Value
This, the measure of center that can be easily determined in a box plot is the MEDIAN, while the measure of variability can be determined by finding the difference between Q3 and Q1, which gives us the interquartile range (IQR).
Therefore, for the box plot given above:
✔️The best measure of center is the median (which is the value at the point where the vertical line divides the rectangular box).
✔️The median is 26
✔️The best measure of variability is the interquartile range
✔️IQR = 29 - 24 = 5

53°
Answer:
307°
Step-by-step explanation:
CF is a diameter of the circle. so, any arc connecting C and F has an arc angle of 180° (half-circle).
so, we need to add the arc angle FD.
we know the arc angle ED = 79°.
so, what is left to add is the arc angle FE.
the arc angle FE is the same as BC.
and the arc angle BC is the supplementary angle (means together they have 180°) to 132° :
BC = 180 - 132 = 48°
therefore,
the arc angle CFD = 180 + 48 + 79 = 307°
the length of a rectangle is 10cm greater than it's width,the perimeter is 70cm.find the length nd width
Step-by-step explanation: TS 5 15 8 36
L = W + 10 cm

Answer: hello the options related to your question is missing attached below are the options
answer : The researcher did not state that the p-value is conditional on the null hypothesis being true ( A )
Step-by-step explanation:
What is wrong with the researcher's interpretation is that the researcher did not state that the p-value is conditional on the null hypothesis being true.
The P-value is a required value when either rejecting or accepting the null hypothesis. and the researcher did not add the clause that the probability of getting a statistic > 1.92 provided the null hypothesis is assumed to be true
A sandwich shop offers a choice of white or wheat bread, three choices for meat (turkey, ham, no meat), and four choices for cheese (Swiss, cheddar, provolone, no cheese).
Answer:
24 different sandwich options can be assembled.
Step-by-step explanation:
Since a sandwich shop offers a choice of white or wheat bread, three choices for meat (turkey, ham, no meat), and four choices for cheese (Swiss, cheddar, provolone, no cheese), to determine how many possible sandwich options can be performed, the following calculation must be performed:
Bread = 2 options
Meat = 3 options
Cheese = 4 options
2 x 3 x 4 = X
6 x 4 = X
24 = X
