Given a sample of female students, n = 7, with SS = 550, and a sample of male students, n = 10, with SS = 720:
- Find the pooled variance for the two samples.
- Compute the estimated standard error for the sample mean difference.
- If the sample mean difference is 5 points, is this enough to reject the Ho for an independent-measures hypothesis test using .01, one-tailed test?
- If the sample mean difference is 20 points, is this enough to reject the Ho for an independent-measures hypothesis test using .01, one-tailed test?
- Compute Cohen's d to measure the effect size for the 5-point difference and for the 20-point difference. Briefly evaluate the effect size of each difference.
