The sample standard deviations and sample sizes are given for independent simple random samples from two populations. Use the two-standard-deviations F-test to conduct the required hypothesis test.

s1 = 26.9, n1 = 61, s2 = 26.3, n2 = 31; right-tailed test, α = 0.01
◦ Test statistic: F = 27.51. Critical value = 2.03. Reject H0.
◦ Test statistic: F = 1.05. Critical value = 2.03. Reject H0.
◦ Test statistic: F = 1.02. Critical value = 2.21. Do not reject H0.
◦ Test statistic: F = 1.05. Critical value = 2.21. Do not reject H0.
