1. a. Using the results from Descriptive Statistics, determine a 95 % confidence interval for the average study time of all students for the test,

 b. Verify these values by generating the interval by hand using the t-table in Appendix D.

2.  It has been hypothesized that, on the average, students study more than five hours for the test. Calculate the t-value for this test in cell B8 using the values for the mean and standard error from the results of Descriptive Statistics. Compare this t-value to the critical t-value found in Appendix D for a = .05. What is your conclusion?
