From a sample of 37 stolen watches, you find that the mean cash value is $950. The standard deviation for your sample is $90. Test the null hypothesis that your sample came from a population whose mean cash value (Mu) is $1,000 against the alternative hypothesis that Mu is different than $1,000. Use alpha = .05. a. Formally state the alternative and the null hypothesis for this test b. What is the critical value(s) for this test? c. Compute and...
