Conduct an Independent Samples T Test (a test of mean differences) using EDUC as the dependent variable (test variable) and SEX as the grouping variable. Define groups so that Group 1 = 1 and Group 2 = 2 (1 = males 2 = females). Set the alpha level at .05.
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 0.05 (alpha level), we fail to reject the null hypothesis.
If the significance level of the obtained t statistic is equal to or less than 0.05 (alpha level), we reject the null hypothesis.
g. Decision: Since the significance level of the obtained t statistic is ____ and it is ____ (less or greater) than 0.05 (alpha level), we _______________ (fail to reject or reject) the null hypothesis.
h.Interpretation/conclusion:
