Columns are: 1) N; 2) Mean; 3) Std. Deviation; and 4) Std. Error Mean.  Results are:  For Female: N = 48. Mean = 6.7917. Std. Deviation = 5.48095. Std. Error Mean = .79111. For Male: N = 52. Mean = 6.0577. Std. Deviation = 6.35367. Std. Error Mean = .88110. Independent Samples Test Results Table: Row 1 is statistics for Concerts when Equal variances are assumed. Row 2 is statistics for Concerts when Equal varianances not assumed.  Columns are: 1) Levene's Test for Equality of Variances  F; 2) Levene's Test for Equality of Variances Sig.; 3) t-test for Equality of Means t; 4) t-test for Equality of Means df; 5) t-test for Equality of Means Sig. (2-talied); 6) t-test for Equality of Means Mean Difference; 7) t-test for Equality of Means Std. Error Difference; 8) t-test for Equality of Means 95% Confidence Interval of the Difference - Lower; 9) t-test for the Equality of Means 95% Confidence Interval of the Difference - Upper.  Results are:  Levene's Test for Equality of Variances: F =.718. Sig.=.399. t-test for Equality of Means: Equal variances assumed. t=.616. df = 98. Sig. (2-tailed) =.539. Mean Difference = .73397. Std. Error Difference = 1.19118. 95% Confidence Interval of the Difference - Lower = -1.62988. 95% Confidence Interval of the Difference - Upper = 3.09782. t-test for Equality of Means Equal variances not assumed. t=.620. df = 97.568. Sig. (2-tailed) =.537. Mean Difference = .73397. Std. Error Difference = 1.8414. 95% Confidence Interval of the Difference - Lower = -1.61604. 95% Confidence Interval of the Difference - Upper = 3.08399.  Is the Levene's Test for Equality of Variances significant? Is the t-test for Equality of Means (Two Mean Independent Samples Test) significant? Based on the t-test significance, how do you answer the research question/hypothesis?
