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 wh 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 o (a) male who increased their time spent on Facebook over the past year. Keep the 4th decimal place in you
