You suspect that students' time spent working in outside jobs increases over the term. For a sample of 25 students, you obtain the number of hours spent working in week 1, and the number of hours for the same students in week 14. The data is in the Excel file. Test the hypothesis that the population mean for week 1 is greater than the population mean for week 14, at a 99% confidence level. Show all parts of the hypothesis test, including your hypotheses, identification/calculation of the necessary values, your test-statistic calculation, your p-value calculation, and your conclusion.
Assume equal or unequal variances if possible
Please Provide Hypothesized Mean Difference as well.
