Question: A major challenge for retailers like Best Buy is showrooming

A major challenge for retailers like Best Buy is “showrooming” which describes customers who browse through their stores and then make their purchase from an online competitor. In an effort to measure the volume of showrooming, Best Buy observes the percentage of customers who leave their stores with a purchase. Suppose Best Buy would like to investigate if the percentage of women who leave the store with a purchase is higher than the percentage of men. A random sample of 170 female shoppers was selected and it was found that 73 left the store with a purchase. A random sample of 150 male shoppers was selected and it was found that 56 left the store with a purchase.
a. Perform a hypothesis test with α = 0.10 to determine if the percentage of women who leave the store with a purchase is higher than the percentage of men.
b. Determine the p value and interpret the results.
