Part One - Hypothesis Tests for this part, make hypothesis tests of the two situations listed below by:

-Constructing an 8-step hypothesis test, showing all calculations,

-Including both the critical value method and the p-value method in the calculations.

-Using the correct terminology and interpretation of the resulting confidence interval for each test.

Hypothesis Test - Situation 1

It has been reported that the mean amount of sleep that adults receive is 7 hours per night. My boss has asked me to look into this statistic by running my own study. I gather 49 adults and find the following information. The mean amount of sleep was 6.2 hours with a standard deviation of 1.8 hours. Based on my results, I claim that adults receive less than 7 hours of sleep. Test my claim with a 0.05 significance level.

Hypothesis Tests - Situation 2

My boss also would like me to look at average sleep for a specific age range (between 35 and 44 years of age). It has been previously reported that 38.3% of adults in this age range receive the recommended amount of sleep per night (at least 7 hours). I decide to test this claim by gathering 32 adults between the ages of 35 and 44 years old. In the sample, I find that 15 of the participants receive at least 7 hours of sleep. Test the claim that more than 38.3% of adults get the recommended amount of sleep per night with a significance level of 0.01.

Part Two - Hypothesis Errors

After I have make my hypothesis tests, in a separate paragraph,

-Explain the possible error(s) that could have occurred and what they imply for each test.
-Explain how I might prevent the error(s) from occurring in future hypothesis tests.
