Recent research by analysts and retailers claims significant gender differences when it comes to online shopping (The Wall Street Journal, March 13, 2008).

A survey revealed that 5,400 of 6,000 men said they “regularly” or “occasionally” make purchases online, compared with 8,600 of 10,000 women surveyed.

At the 5% significance level, test whether the proportion of all men who regularly or occasionally make purchases online is greater than the proportion of all women.
