An Internet survey asked 525 Facebook users whether the amount of time they spent using Facebook was increased over the past year. The response of the survey is "Increase", with values "Yes" and “No". Additionally, gender information was collected in the survey. The data is summarized in the following table. Gender X p = X/n n Female 292 47 0.1610 Male 233 21 0.0901 Total 525 68 0.1295 In the table, the n column gives the sample size for each group, X column gives the number of users who increased their use of Facebook over the past year, and p column gives the sample proportion. Find the 95% confidence interval for the difference between the proportion of female and that of male who increased their time spent on Facebook over the past year. Keep the 4th decimal place in your numerical answer. It was claimed that the proportion who increased the time spent on Facebook over the past year would be higher for female than for male. Do you think the data support such claim? Do a hypotheses test to support your conclusion. Choose the significance level to be 0.01.
