I am having a hard time working through this problem.

Exercise 12-10. There are many different ways to test a hypothesis. In chapter 12 in the textbook, we explained how to use a two- sided and a one-sided t-test. In the space following, please explain the circumstances under which you would use a one-sided t-test and a two-sided t-test. Next, use the hypothetical sample data in table 12-4 to perform a sample t-test testing the sample mean against a test value of 1. Use the 95 percent confidence level and calculate the critical & value using both a one-sided and two-sided test. How do these calculations illustrate the difference between the two tests?
