1. The owner of a construction company would like to know if his current work crew takes on average less time to build a deck on a house than his past crews. He knows that the average time it took his past crews to build a deck is 28 hours. A random sample of 9 decks that the current crew has built resulted in a sample mean of building time of 24 hours and a sample standard deviation of 6 hours. Conduct the appropriate hypotheses test using the α = 0.05 and Critical Value method. Assume that times it takes his current crew to build the decks are normally distributed.

a. Define H_{0} and H_{a}

b. Find the test statistic and critical value(s) and draw the rejection region(s) labeling the observed and critical value(s).

c. State conclusion and interpretation.

2. Suppose your p-value = 0.034 and a = 0.05. Do we reject or fail to reject H_{0}?
