Transcribed Image Text:Small-business telephone users were surveyed 6 months after access to carriers other than Carrier A became available for wide-area telephone service. Of a random sample of 210 Carrier A users, 107 said they were attempting to
learn more about their options, as did 211 of an independent random sample of 290 users of alternate carriers. Test, at the 5% significance level against a two-sided alternative, the null hypothesis that the two population proportions
are the same.
