On part D; the second blank choices are not enough/enough
For the given data, (a) find the test statistic, (b) find the standardized test statistic, (c) decide whether the standardized test statistic is in the rejection region, and (d) decide whether you should reject or fail to reject the null hypothesis. The samples are random and independent. Claim: 4, <H2, a =0.01. Sample statistics: x, = 1225, n, = 40, x2 = 1205, and n2 = 60. Population statistics: o, = 75 and o, = 100. (a) The test statistic for u, -H2 is (b) The standardized test statistic for u -P2 is (Round to two decimal places as needed.) (c) Is the standardized test statistic in the rejection region? No Yes (d) Should you reject or fail to reject the null hypothesis? Hn. At the 1% significance level, there is V evidence to support the claim. Reject Fail to reject
