Question:

=+Suppose that an analyst at SmartWool wanted to test if the proportion of visits resulting in a sale from the new website has changed from the 0.20 it was historically. Suppose she also wants to know if the mean sale has increased from the average $24.85 that it was with the old site. To do that she collects a representative sample of 200 visits since the new website went online and finds that the sample proportion is 0.29 with a P-value of 0.00146. From the 58 sales in the sample, she finds that they spent $26.05 on average with a standard deviation of $10.20 for a P-value of 0.1870. What conclusions can she draw if she uses an a level of 0.05?
