27 25

25 29

19 18

10 23

16 20

22 15

14 19

- What statistical test should be done to analyze these data?
- Identify Ho and Ha for this study.
- Conduct the appropriate analysis.
- Should Ho be rejected? What should the researcher conclude?
- If significant, compute and interpret the effect size.

Step 1

1.

Here the samples are drawn from the normal population and the population standard deviations are unknown.

Thus, we can use t- test for difference in means of male and female

Step 2

2.

The null and alternative hypotheses are stated below:
