A market analyst wants to know if the new website he designed is showing increased page views per visit. A customer is randomly sent to one of two different websites, offering the same products but with different designs, and the number of page views from the website is recorded. For the 80 customers who viewed the new website design, the average number of page views was 7.7 with a standard deviation of 4.6 pages. For the 95 customers who viewed the original website design, the average number of pages views was 7.3 with a standard deviation of 4.3 pages. Calculate the margin of error for a 90% confidence interval for the true difference (new website minus old) in mean page views. Round your answer to 3 decimal places.
