Question
(c) Test if H <0 at the a=0.05 level of significance. What are the oorrect null and alternative hypotheses? OA Ho: Ha <0 OB. Hg: Ha <0 H1: Ha >0 H: Ha =0 OC. H: H 0 OD. H: Pg 0 H1: Ha <0 P-value = (Round to three decimal places needed.) Choose the correct conclusion below. O A. Reject the null hypothesis. There is insufficient evidence that p, <0 at the a= 0.05 level of significance O B. Do not reject the null hypothesis. There is insufficient evidence that g <0 at the a= 0.05 level of significance. OC. Reject the null hypothesis. There is sufficient evidence that , <0 at the a= 0.05 level of significance. O D. Do not reject the null hypothesis. There is sufficient evidence that p, <0 at the a = 0.05 level of significance. (d) Compute a 95% confidence interval about the population mean difference Ha- The lower bound is The upper bound isO (Round to two decimal places needed.)
