The following observations are from two independent random samples, drawn from normally distributed populations.

Sample 1 [59.79, 79.13, 61.82, 55.15, 73.43, 56.37]

Sample 2 [66.05, 66.93, 60.02, 64.24, 60.1]

Test the null hypothesis H0:σ21=σ22 against the alternative hypothesis HA:σ21≠σ22.

a) Using the larger sample variance in the numerator, calculate the F test statistic. Round your response to at least 3 decimal places.

Independent random samples, each containing 80 observations, were selected from two populations. The samples from populations 1 and 2 produced 16 and 10 successes, respectively. Test H0:(p1−p2)=0 against Ha:(p1−p2)≠0. Use α=0.1 (a) The test statistic is (b) The P-value is (c) The final conclusion is A.
