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 240 Carrier A users, 135 said they were attempting to learn more about their options, as did 227 of an independent random sample of 260 users of alternate carriers. Test, at the 1% significance level against a two-sided alternative, the null hypothesis that the two population proportions are the same. Click the link to view a standard normal distribution table. Let Px be the proportion of Carrier A users who said they were attempting to learn more about their options and Py be the proportion of users of alternate carriers who said they were attempting to learn more about their options. Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: Px-Py=0 H₁: Px-Py 20 D. Ho: Px-Py #0 H₁: Px-Py = 0 The test statistic is Z= B. Ho: Px-Py = 0 H₁: Px-Py <0 E. Ho: Px-Py = 0 H₁: Px-Py #0 (Round to two decimal places as needed.) O C. Ho: Px-Py = 0 =0 H₁: Px-Py ≤0 OF. Ho: Px-Py = 0 H₁: Px-Py >0
