 Critical values question The table shows the number satisfied in their work in a sample of working adults with a college education and in a sample of working adults without a college education. Assume that you plan to use a significance level of alpha=0.05 to test the claim that p1>p2. Find the critical value(s) for this hypothesis test. Do the data provide sufficient evidence that a greater proportion of those with a college education are satisfied in their work?                                                    College Education      No college education     Number in sample                                194                                  188                        number satisfied in their work           74                                    70The answer that I got was z=1.645;no.A)z=1.645;noB)z=-1.645;yesC)z=1,96;yesD)z=+-1.96;no Read 69 times 5 Replies

 alpha = 0.050.05 / 2 = 0.025, which has a z = ± 1.96 Choose D
