Conduct the following test at the alphaequals0.01 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the critical value. Assume that the samples were obtained independently using simple random sampling. Test whether p 1 not equals p 2. Sample data are x 1 equals 30, n 1 equals 254, x 2 equals 38 and n 2 equals 301. Question content area bottom Part 1 (a) Determine the null and alternative hypotheses. Choose the correct answer below. Upper H 0 : p 1 equals p 2 versus Upper H 1 : p 1 greater than p 2 Upper H 0 : p 1 equals p 2 versus Upper H 1 : p 1 less than p 2 Upper H 0 : p 1 equals p 2 versus Upper H 1 : p 1 not equals p 2 Part 2 (b) The test statistic z 0 is negative 0.289. (Round to two decimal places as needed.) Part 3 (c) The critical values are plus or minus 2.576. (Round to three decimal places as needed.) Part 4 Test the null hypothesis. Choose the correct conclusion below. Do not reject the null hypothesis. Reject the null hypothesis
