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. The accompanying table shows the data from

30

randomly chosen customers from each website. Test the null hypothesis that the mean number of page visits is the same for the two websites.? (This is a? two-sided test.) Assume that the data come from a population that is Normally distributed. Complete parts a through f below.

3) Find the value of the tstatistic for the difference in sample mean page visits, 9A - 9B! for the null hypothesis. t= El (Round to two decimal places as needed.) b) Calculate the degrees of freedom from the formula df= df = D (Round to two decimal places as needed.) c) Calculate the degrees of freedom using the rule that df= min (n1 - 1, n2 -1) . df= |:| (Round to two decimal places as needed.) of) Find the Pvalue using the degrees of freedom from part b. The P-value is D. (Round to three decimal places as needed.) e) Find the Pvalue using the degrees of freedom from part c. The Pvalue is D. (Round to three decimal places as needed.) f) What do you conclude at 0: = 0.10? |:| H0 for both cases. There El sufcient evidence to reject the claim that the mean number of page views is the same for both websites.
