We are 99% confidence that the main difference is between_and_. Round to two decimal places as needed use ascending order. 

(b) Construct a 99% confidence interval about p, -P2. 14.7 19.8 3.3 3.1 P= 0.000 (Round to three decimal places as needed.) Should the null hypothesis be rejected? C A. Reject Ho, there is sufficient evidence to conclude that the two populations have different means. O B. Do not reject Ho, there is sufficient evidence to conclude that the two populations have different means, O C. Do not reject Ho, there is not sufficient evidence to conclude that the two populations have different means. OD. O D. Reject Ho, there is not sufficient evidence to conclude that the two populations have different means. (b) Construct a 99% confidence interval about p, - ,.
