(a) describe how you could construct a bootstrap distribution to estimate the standard error of the proportion in this situation.
(b) one such distribution, based on proportions from 5000 bootstrap samples. the standard deviation of these proportions is 0.0102. use this information to find a 99% confidence interval for the propor- tion of cell phone users (in 2010) who have downloaded at least one app to their phone.
