Not happy with the previous results, the analyst in Exercise 2 takes a much larger random sample of cus- tomers from each website and records their page views. Here are the data:

Website 1

Website 2

n1  = 80

1 = 7.7 pages

s1  = 4.6 pages

n2  = 95

2 = 7.3 pages

s2  = 4.3 pages

a) Find the estimated mean difference in page visits be- tween the two websites.

b) Find the standard error of the estimated mean difference.

c) Calculate the t-statistic  for  the  observed difference in mean page visits assuming that the true mean difference is 0.
