About 5% of hourly paid workers in a regioner the prevailing minimum wage or less A grocery chain offers discount rates to companies that have at least 30 employees who earn the prevailing minimum wage or less Complete parts
through (c) below
(a) Company Ahas 281 employees What is the probability that Company A will get the discount?
(Round to four decimal places as needed)
Answer:
0
Step-by-step explanation:
Let X to be a random variable that looks a binomial distribution which denoted the number of employees out of the 281 who earn the prevailing minimum wage or less
The sample size n = 281
The population parameter p = 5% = 0.05
Using normal approximation for the mean.
[tex]\mu = np[/tex]
[tex]\mu = 281\times 0.05[/tex]
[tex]\mu = 14.05[/tex]
The standard deviation is:
[tex]\sigma = \sqrt{np(1-p)}[/tex]
[tex]\sigma = \sqrt{281 \times 0.05(1-0.05)}[/tex]
[tex]\sigma = \sqrt{281 \times 0.05(0.95)}[/tex]
[tex]\sigma = \sqrt{13.3475}[/tex]
[tex]\sigma =3.6534[/tex]
By using continuity correction; the sample mean x is:
x = 30 - 0.5
x = 29.5
The z statistic test can now be as follows:
[tex]Z = \dfrac{x-\mu}{\sigma}[/tex]
[tex]Z = \dfrac{29.5-14.05}{3.6534}[/tex]
[tex]Z = \dfrac{15.45}{3.6534}[/tex]
Z = 4.23
Thus, the probability that company A will get a discount is
P(X ≥ 30) = P(Z >4.23)
= 1 - P(Z < 4.23)
By using the Excel function for the z score 4.23 i.e. "=1 - NORMSDIST(4.23)" we get;
= 0.0000
Let X be a random variable that shows how many employees out of 281 earn the prevailing minimum wage or less.
X does have a binomial distribution with parameters [tex]n = 281 \ \ and\ \ p = 0.05[/tex]:
Since [tex]np \ \ and\ \ n(1-p)[/tex] are greater than 5, X does have a normal distribution of parameters when using the normal approximation.
[tex]\to \mu= np=281 \times 0.05= 14.05[/tex]
Calculating the standard deviation:
[tex]\to \sigma=\sqrt{np(1-p)}\\\\[/tex]
[tex]= \sqrt{281 \times 0.05 (1-0.05)}\\\\=\sqrt{281 \times 0.05 \times 0.95}\\\\ =\sqrt{14.05 \times 0.95}\\\\ =\sqrt{13.3475}\\\\=3.653[/tex]
Continuity correction is required in this case. The z-score for [tex]X = 30-0.5 = 29.5[/tex]:
[tex]\to z= \frac{X- \mu}{\sigma}[/tex]
[tex]=\frac{29.5-14.05}{3.653}\\\\=\frac{15.45}{3.653}\\\\=4.2294\\\\[/tex]
The likelihood that Company Its will receive the discount:
[tex]\to P(X\geq 30)=P(z>4.229)=0.0000117\approx \ 0.0000[/tex]
Therefore, the final answer is "0".

Kim ran a mile in PE class. After resting for 1 hour her heart rate was 75 beats per minute. If her heart rate decreased by ⅖ , what was it immediately after she ran the mile?
Answer:
125
Step-by-step explanation:
since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.

Answer:
A. Initial value 12, rate of change -2
Step-by-step explanation:
We note that the x-values in the table go up by 1 and the y-values go down by 2. That "down by 2" for "up by 1" is the rate of change: -2/1 = -2.
If we extend the table upward one more row, we have x=0 and y=12. That is, the "initial value" is 12.
The initial value is 12; the rate of change is -2.
