A researcher wishes to compare two different groups of students with respect to their meantime to complete a particular task. The time required is determined for each group. The datasummary is given below. Test the claim at a= 0.05, that there is no difference in variance. Give the critical region, test statistic value, and conclusion for the F test. n1=100, s1=20
This posting provides solution to a hypothesis testing problem for testing of means to complete a task of two groups with no differnce in variance.
