- You are given the null and alternative hypotheses and the sample information shown below. Complete parts a and b below. Sample 2 n2 = 125 S2 = 33 X2 = 120 Ho H1-H2=0 Sample 1 n1= 130 S1 = 38 X1 = 145 a. Develop the appropriate decision rule, assuming a significance level of 0.01 is to be used. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) A. Reject Ho if t O C. Reject Ho if t> b. Test the null hypothesis and indicate whether the sample information leads you to reject or fail to reject the null hypothesis. Use the test statistic approach. Calculate the value of the test statistic. t%=(Round to two decimal places as needed.) Since the test statistic V in the rejection region, V the null hypothesis. There is V evidence at a = 0.01 to conclude that the two population means are different.Assume a significance level of a = 0.05 and use the given information to complete parts (a) and (b) below. Original claim: More than 44% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.0254. 2 N a.

Is the percentage of college students who are volunteers larger for students receiving financial aid? Of the 377 randomly selected students who receive financial aid, 72 of them volunteered their time. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ?v Select an answer (please enter a decimal) H: ? v Select an answer v (Please enter a decimal) c. The test statistic ? v (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? a f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ...
