Assume that the differences are normally distributed. Complete parts (a) through (d) below.
P-value= (Round to three decimal places as needed.)
Choose the correct conclusion below.
O A. Do not reject the null hypothesis. There is sufficient evidence that μg <0 at the a= 0.05 level of significance.
O B. Do not reject the null hypothesis. There is insufficient evidence that µ <0 at the a= 0.05 level of significance.
O C. Reject the null hypothesis. There is insufficient evidence that Hd <0 at the α = 0.05 level of significance.
O D. Reject the null hypothesis. There is sufficient evidence that μ <0 at the a = 0.05 level of significance.
(d) Compute a 95% confidence interval about the population mean difference -
The lower bound is
