A study of the cell phone market in the USA seeks to investigate the use of iOS vs'Android operating systems. In a random sampling of 60 cell phone users, 65% use the iOS system. In another random sampling of 80 cell phone users, 40% use the Android system. Assuming alpha =0.05, answer the following questions and test the claim that the proportion of iOS systems among cell phone users is higher than that of Android systems. The value of p-bar ( pooled p)= (round to 3 decimals) The left critical value = (round to 2 decimals - if there is no left value, enter "na") The right critical value = (round to 2 decimals - if tr)ere is no right value, enter "na") The test statistic = (round to 2 decimals) What is the result of the hypothesis test? (enter "reject HO " or "fail to reject HO") s the claim supported? (enter "yes" or "no")
