H 0: = 15
H a: 15
A sample of 50 provided a sample mean of 14.28. The populationstandard deviation is 7.
a. Compute the value of the teststatistic (to 2 decimals). (If answer is negative, use minus “-“sign.)
b. What is the p-value (to4 decimals)?
c. Using = .05, can it beconcluded that the population mean is not equal to 15? Select:(Yes or No) Item.
Answer the next three questions using the critical valueapproach.
d. Using = .05, what are thecritical values for the test statistic (to 2 decimals)? ±
e. State the rejection rule:Reject H 0 if z is Select:(greater than or equal to, greater than, less than or equalto, less than, equal to, or not equal to) thelower critical value and is Select: (greater than or equal to,greater than, less than or equal to, less than, equal to, not equalto) the upper critical value.
f. Can it be concluded that thepopulation mean is not equal to 15?Select: (Yes or No).
