Although women tend to visit social-networking sites somewhat more frequently than men, the recent social media phenomenon Pinterest is an extreme example with 83 % of the users being female in the United States. The usage is so one-sided that Time Magazine declared "Men are from Google+, Women are from Pinterest." An SRS of 520 Pinterest users is to be taken. (a) What are the mean and standard deviation of pˆ p ? answer to 4 decimal places μpˆ μ p (± 0.0001) = σpˆ σ p (± 0.00001) = (b) What is the approximate probability that the sample pˆ p is between 80 % and 86 %? This is the chance that pˆ p estimates p p within 3 %. (Use normalcdf for this calculation)
