In 2012 the CDC reported that the average American adult spent 17 minutes per day exercising. To determine if the average amount of time spent exercising has changed for American adults, a researcher takes a sample of 40 adults from across the US and finds them to exercise an average of 18.2 minutes with a standard deviation of 5.5 minutes. At o = 0.05, conduct a hypothesis test to determine if the average amount of time spent exercising has changed.

a. Enter your hypothesis here if necessary, use mu or sigma for u or o and =/= for #. (you may also use math entry mode).

b. Rind the test statistic (Round of to four decimal places)

c. Enter the critical value. If it is two-talled test, enter the positive critical value

d. What is the p-value for the test?

e. What conclusion did you reach regarding Ho?

• Reject Ho?

Please round your answers four decimal places. If an answer comes out exactly to fewer decimal places, just enter as many as you have.

• Accept Ho?
• Do not reject Ho

f. Write a conclusion to your hypothesis
