Use this information to find a 95% confidence interval for the proportion of cell phone users (in 2010) who have downloaded at least one app to their phone. 0.25 0.26 0.27 0.28 0.29 0.30 0.31 0.32 0.33 30phat Bootstrap distribution for the proportion of cell phone users who have downloaded an app Round your answers to three decimal places.
