Researchers conducted a study of smartphone use among adults. A cell phone company claimed that iPhone smartphones are more popular with males than females. The results of the survey indicate that of the 232 female cell phone owners randomly sampled, 5% have an iPhone. Of the 1,343 male cell phone owners randomly sampled, 10% own an iPhone. Test at the 5% level of significance. Is the proportion of male iPhone owners greater than the proportion of female iPhone owners? Make sure you clearly state your null and alternative hypothesis. Specify the p-value
