Small-business telephone users were surveyed 6 months after access to carriers other than Carrier A became available forwide-area telephone service. Of a random sample of 240 Carrier A users, 135 said they were attempting to learn more about theiroptions, as did 227 of an independent random sample of 260 users of alternate carriers. Test, at the 1% significance level againsta two-sided alternative, the null hypothesis that the two population proportions are the same.Click the link to view a standard normal distribution table.be theLet Px be the proportion of Carrier A users who said they were attempting to learn more about their options and Pyproportion of users of alternate carriers who said they were attempting to learn more about their options.
