The residuals are normally distributed. b. The model over predicts the value of the dependent variable for small values and large values of the independent variable. c. The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship. d. The residuals have a constant variance.

Answer: Hello the scatter plot related to your question is missing attached below is the scatter plot
answer : The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship ( C )
Step-by-step explanation:
The conclusion that can be drawn based upon the scatter chart is that The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship
A scatter plot helps in observing the relationship within different numeric variables but the scatter plot attached fails in the showing the actual relationship

3. (G.11C) A right cylinder has a total surface area of 1301 cm?. If the diameter of
the cylinder is 10 cm, what is the height?
X
A 8 cm
B 10 cm
C 9 cm
D 12 cm
Answers
Answer:
A. 8 cm
Step-by-step explanation:
Total surface of a cylinder = 130π cm²
Diameter (d) = 10 cm
Radius (r) = 10/2 = 5 cm
Height = ?
Formula for total surface area of cylinder = 2πrh + 2πr²
Plug in the values
130π = 2*π*5*h + 2*π*5²
130π = 10hπ + 50π
130π = π(10h + 50)
Divide both sides by π
130 = 10h + 50
Subtract 50 from each side
130 - 50 = 10h
80 = 10h
Divide both sides by 10
80/10 = 10h/10
8 = h
h = 8 cm

What is the equation of a circle with a center at (4,-9) and a radius of 5?
Answers
Answer:
(x - 4)² + (y + 9)² = 5²
Step-by-step explanation:
The standard form equation is
(x - h)² + (y - k)² = r²
(h, k) is the center
r is the radius
----------------------------
Given (h, k) = (4, -9) and r = 5
(x - 4)² + (y + 9)² = 5²

What is the radius of a sphere with a volume of 1203 cm', to the nearest tenth of a
centimeter?
Answers
Answer:
The radius of the sphere is of 6.6 centimeters.
Step-by-step explanation:
Volume of an sphere:
The volume of an sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In this question:
[tex]V = 1203 \text{cm}^{3}[/tex]
Replacing into the equation, we find the radius, in centimeters. So
[tex]V = \frac{4\pi r^3}{3}[/tex]
[tex]1203 = \frac{4\pi r^3}{3}[/tex]
[tex]r^3 = \frac{1203*3}{4\pi}[/tex]
[tex]r = \sqrt[3]{\frac{1203*3}{4\pi}}[/tex]
[tex]r = 6.6[/tex]
The radius of the sphere is of 6.6 centimeters.

While debating which greeting he should use when calling potential customers — "Howdy!" or "Hiya!" — he decided to conduct a small study. For his subsequent 500500500 calls, he chose one of the greetings randomly by flipping a coin, and used the same script for his sale otherwise. Then, he compared the percentage of calls he succeeded in selling insurance using each greeting. He noticed that he was significantly more likely to make a sale in calls that started with "Hiya!" Can we conclude that the greeting caused the difference in sales? Why? Choose 1 answer:
Answers
Answer:
Yes, because the calls were each randomly assigned a greeting.
Step-by-step explanation:
It is given that Andrew who works at the call center of an insurance company, decided to conduct a small survey on how to greet the potential customers while calling.
For this, he uses his 500 subsequent calls and he chooses to greet his customers randomly as "Howdy" or "Hiya".
Since the selection bias is ruled out, the calls were randomly assigned for the greetings. Thus the greetings caused a difference in sales.
Answer:
Yes, because the calls were each randomly assigned a greeting

The percentage of historical
From the table, we have:
[tex]Historical = 2[/tex]
and
[tex]Total = 6+3+7+2+7[/tex]
[tex]Total = 25[/tex]
So, the percentage of historical is:
[tex]\%H = \frac{Historical}{Total} * 100\%[/tex]
This gives:
[tex]\%H = \frac{2}{25} * 100\%[/tex]
[tex]\%H = \frac{200\%}{25}[/tex]

b. Pulse rates for students at the beginning of class are being compared to pulse rates for the same students at the end of class.
c. The weights of 10-year-olds in 2009 are being compared to the weights of 10- year-olds in 1994.
Answers
Answer:
A = Not a paired sample
B = paired sample
C = Not a paired sample
Step-by-step explanation:
Paired samples also commonly referred to as dependent samples are often characterized by having to different data points which are taken at different times, location and so on. Such that each pair of data points or observation can be matched based on the basis of the subject or sample name usually for the sake of analysing if any statistical difference exists between the occurrence of each observation.
For the instances given above ;
a.) this isn't a paired sample, because Professor Quick and Professor Quacks students are different, hence each student has only one reading and as such a match of the two test scores cannot be made on the basis of student name or identity. Hence, it is not a paired sample
B.) This is a paired sample, two different readings are available for each students ; one at the beginning, the other at the end. Hence, it is a paired sample
C.) This is not a paired sample, because the subjects used to obtain the weight of 10 year old in 1994 aren't the same samples used in 2009
