Question
A market analyst wants to know if the new website he designed is showing increased page views per visit and calculates the summary statistics in the table to the right. Assume that the new website is website 1 and the old website is website 2. Test the hypothesis that the mean number of page views from the two websites is the same. You may assume that the number of page views from each website follow a Normal distribution. Complete parts a through c below. a) Calculate the value of the statistic given that the approximation formula gives d = 66.9. The P-value is Round to four decimal places as needed.)Explanation / Answer
Solution:
a) Calculate the P-value of the statistic given that the approximation formula gives df = 166.9
It is a two-sided test.
The P-value is = 2*P(t with df=167 >0.376) = 0.7074 (from student t table)
The P-value is 0.7074
