Hello- can you please help me with this problem. See week 2, problem 1, on the attached deck. Week 2 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. 1 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? Males Females Ho: Mean salary = 45.00 Ho: Mean salary = 45.00 Ha: Mean salary =/= 45.00 Ha: Mean salary =/= 45.00 Note: While the results both below are actually from Excel’s t-Test: Two-Sample Assuming Unequal Variances, having no variance in the Ho variable makes the calculations default to the one-sample t-test outcome – we are tricking Excel into doing a one sample test for us. Male Ho Female Ho Mean 52 45 Mean 38 45 Variance 316 0 Variance 334.666666666667 0 Observations 25 25 Observations 25 25 Hypothesized Mean Difference 0 Hypothesized Mean Difference 0 df 24 df 24 t Stat 1.96890382662054 t Stat -1.91320635733238 P(T<=t) one-tail 0.0303078502888749 P(T<=t) one-tail 0.0338621184371692 t Critical one-tail 1.71088207990943 t Critical one-tail 1.71088207990943 P(T<=t) two-tail 0.0606157005777499 P(T<=t) two-tail 0.0677242368743384 t Critical two-tail 2.06389856162802 t Critical two-tail 2.06389856162802 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Conclusion: Do not reject Ho; mean equals 45 Note: the Female results are done for you, please complete the male results. Is this a 1 or 2 tail test? Is this a 1 or 2 tail test? 2 tail - why? - why? Ho contains = P-value is: P-value is: 0.0677242368743384 Is P-value < 0.05 (one tail test) or 0.025 (two tail test)? Is P-value < 0.05 (one tail test) or 0.025 (two tail test)? Is P-value < 0.05 (one tail test) or 0.025 (two tail test)? Is P-value < 0.05 (one tail test) or 0.025 (two tail test)? No Why do we not reject the null hypothesis? Why do we not reject the null hypothesis? Why do we not reject the null hypothesis? Why do we not reject the null hypothesis? P-value greater than (>) rejection alpha Interpretation of test outcomes:
