Answer:
The p value for this case would be given by:
For this case since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly different from 31.3 MPG
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean is equal to 31.3 MPG, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we know the population deviation, the statistic is given by
(1)
Replacing we got:
The p value for this case would be given by:
For this case since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly different from 31.3 MPG

The data and assuming shows that the company that would give Donna a stable long-term investment is A. eye remember enterprises; the smaller deviation indicates that eye enterprises have less variability in its closing prices than masterful pocket watches.
<h3>How to illustrate the information?</h3>
It should be noted that the information given implies that Donna needs a stable long term investment.
In this case, it's appropriate that the company that has the less standard deviation should be chosen.
This illustrates that Perfect Plungers has less variability.

Answer: Function 1
Step-by-step explanation:
Function 1 has rate of change of
(15.75 - 14.25)/(1 -(-1)) = 0.75. This was calculated using slope formula.
Function 2 has rate of change of 5/6, which is 0.833.
