Then the students measured each others' heights in centimeters, without shoes. The data provided are for the men, with their believed heights converted from inches to centimeters. Assume that conditions for t-tests hold. Complete parts a and b below. Click the icon to view the data. a. Find a 95% confidence interval for the mean difference as measured in centimeters. Does it capture 0? What does that show? The 95% confidence interval for measured - believed is (]]). (Round to three decimal places as needed.) The interval include 0, so a hypothesis that the means are equal be rejected. b. Perform a t-test to test the hypothesis that the means are not the same. Use a significance level of 0.05. Determine the hypotheses for this test. Let Hdifference be the population mean difference between measured and believed height, in centimeters. Choose the correct answer below. O A. Ho: Hdifference = 0 O B. Ho: Hdifference = 0 Ha : H difference 0 Ha: Hdifference > 0 Find the test statistic for measured - believed for this test. t=(Round to two decimal places as needed.) Find the p-value for this test. p-value = (Round to three decimal places as needed.) What is the conclusion for this test? O A. Do not reject Ho. The means of measured and believed heights are not significantly different. O B. Reject Ho. The means of measured and believed heights are not significantly different. O C. Reject Ho. The means of measured and believed heights are significantly different. O D. Do not reject Ho.
