Extracted text: Outcome A В DO Determine (a) the x test statistic, (b) the degrees of freedom, (c) the critical value using a = 0.05, and (d) test the hypothesis at the a= 0.05 level of significance. Observed 53 54 46 47 Expected 50 50 50 50 1 Ho: PA = PB = Pc = Pp = 4 H,: At least one of the proportions is different from the others. .. (a) The test statistic is (Type an exact answer.) (b) There are degrees of freedom. (c) The critical value is. (Round to three decimal places as needed.) (d) Should the null hypothesis be rejected? O A. 2 No because xó is greater than X0.05: O B. 2 Yes because xó is greater than xō.05· 2 OC. Yes because 2 is less than or equal to xo.05: O D. No because xó is less than or equal to x0.05·
