Below you can find the study hours of 6 female students and 5 male students.
To perform a t-Test, execute the following steps.
1. First, perform an F-Test to determine if the variances of the two populations are equal. This is not the case.
2. On the Data tab, in the Analysis group, click Data Analysis.

3. Select t-Test: Two-Sample Assuming Unequal Variances and click OK.
4. Click in the Variable 1 Range box and select the range A2:A7.
5. Click in the Variable 2 Range box and select the range B2:B6.
6. Click in the Hypothesized Mean Difference box and type 0 (H0: μ1 - μ2 = 0).
7. Click in the Output Range box and select cell E1.
8. Click OK.
Result:
Conclusion: We do a two-tail test (inequality). lf t Stat < -t Critical two-tail or t Stat > t Critical two-tail, we reject the null hypothesis. This is not the case, -2.365 < 1.473 < 2.365. Therefore, we do not reject the null hypothesis. The observed difference between the sample means (33 - 24.8) is not convincing enough to say that the average number of study hours between female and male students differ significantly..
