n a research project, researchers collected demographic andhealth data from a sample of elderly residents in the community. Toexamine any possible gender differences in their sample, they wantto see if the females and the males differ significantly on theeducation level (number of years of formal schooling). Theresearchers are not predicting any direction in the possible genderdifferences so the hypotheses should be non-directional. They wouldlike to run a two-tailed test with ? = .10.

1. Calculate estimated variance for population for population 1(S1^1) and (S2^2)
2.Calculate the pooled variance (Spooled2) from the twopopulation variances
3.Use the pooled variance (from question f above) to calculatethe variance for sampling distribution 1 (SM12) and the variancefor sampling distribution 2 (SM22?
4.Calculate standard deviation (Sdiffmean)of the comparisondistribution
5. calculate t statistic and critical t values
