From Problem 3:

Using the file GSS2012, we want to test the following:

Some economists have theorized that one of the reasons that men earn higher incomes than women is that men work longer hours (HRS1). Conduct a statistical test to determine whether this contention is true. Use a 5% significance level for all tests. Compare male and female American adults (SEX: 1 = Male, 2 = Female)

GSS2012.xlsx

Split the observations into two groups:

  • Group 1: Male
  • Group 2: Female

Using summary statistics and graphics (e.g., box plots or histograms) to explore whether there is evidence of a difference in hours worked by gender. Show your work on the PDF file and make your conclusion without performing a formal hypothesis test.

1.Based on the exploratory analysis, did you find any difference in hours worked between both groups (Yes/No) there is a difference?

2.From Problem 3:Perform the appropriate hypothesis test and report the value of the F-test (F-calculated)

3.From Problem 3, report the value of the F-critical (relevant value is in the upper tail) with 4 decimals. You can also report the p-value relevant for this problem.

4.From Problem 3, report the select the answers from the given choices You(reject, not reject) the null hypothesis for the F-test and perform an (equal, unequal) variances t-test.

5.From Problem 3, conduct the test to compare 2 population means and produce a probability distribution graph of reference for the test statistic (graph to be attached and graded in the pdf file).

6.Report the t-test (t-calculated), including negative sign if needed.

7.From Problem 3, report the p-value for this test (2 decimals)

8.From Problem 3, select the answers from the given choices.Thus, we are performinga/an(upper, lower or two) tail(s) test. The conclusion is that we (reject, not reject) the null hypothesis.

8.From Problem 3:State the conclusion of the procedure (be sure to mention the scope of the inference).

9.From Problem 3:Calculate a 95% confidence interval for the difference of means of hours worked between Group 1 and Group 2 (i.e.1-2,). Report the LB

10.From Problem 3:Calculate a 95% confidence interval for the difference of means of hours worked between Group 1 and Group 2 (i.e.1-2,). Report the UB
