Question: A teacher wishes to compare two different groups of students with respect to their mean time to complete a standardized test. The time required is determined for each group. The data summary is given below. Test the claim at α = 0.10, that there is no difference in variance. Give the critical region, test statistic value, and conclusion for the F test.
n₁ = 60 s₁ = 48
n₂ = 60 s₂ = 65
α = 0.10
??State the null and alternate hypotheses
??Determine which test statistic applies, and calculate it
??Determine the critical region
??State your decision: Should the null hypothesis be rejected
