4.Conduct an Independent Samples t Test (a test of mean differences) to investigate whether the self-employed have different levels of education than people employed by someone else. Use the Independent Samples t Test command with EDUC as the dependent variable (test variable) and WRKSLF as the grouping variable. Define groups so that Group 1 = 1 and Group 2 = 2 (1 = self-employed 2 = works for someone else). Set the alpha level at .01.

a. State the null and research hypotheses:

H₀:

H₁:

b. Is the F statistic for Levene's test significant?

c. What is the alpha level for the t-test?

d. Obtained t-value:

e. Significance level for the t-test:

f. Decision rule:

If the significance level of the obtained t statistic is greater than ____ (alpha level), we fail to reject the null hypothesis.

If the significance level of the obtained t statistic is equal to or less than ____ (alpha level), we reject the null hypothesis.

g. Decision: Since the significance level of the obtained t statistic is _____ and it is __________(greater or less) than ____ (alpha level), we ________(reject or fail to reject) the null hypothesis.

h. Interpretation/conclusion:
