Statistics for Managers - 5 questions about T-Tests - excel document
| Testing means - T-tests |
| In questions 2, 3, and 4 be sure to include the null and alternate hypotheses you will be testing. |
| In the first 4 questions use alpha = 0.05 in making your decisions on rejecting or not rejecting the null hypothesis. |
| Below are 2 one-sample t-tests comparing male and female average salaries to the overall sample mean. |
| (Note: a one-sample t-test in Excel can be performed by selecting the 2-sample unequal variance t-test and making the second variable = Ho value - a constant.) |
| Note: These values are not the same as the data the assignment uses. The purpose is to analyze the results of t-tests rather than directly answer our equal pay question. |
| Based on these results, how do you interpret the results and what do these results suggest about the population means for male and female average salaries? |
