#10

10. Summary statistics are given for independent simple random samples from two populations. Use the pooled t-test to conduct the required hypothesis test. x1 = 11.1, s1 = 4.5, n1 = 14, x2 = 17.2, s2 = 4.9, n2 = 17 Perform a two-tailed hypothesis test using a significance level = 0.05. A) Test statistic: t = -3.577 Critical value = 11.699 Do not reject HO B) Test statistic: t = -1.841 Critical value = 12.045 Do not reject HO C) Test statistic: t = -1.841 Critical value = +1.699 Reject H O D) Test statistic: t = -3.577 Critical value = 12.045 Reject H O
