(b) Find the test statistic z and the p-value for testing the hypotheses of part a. Use the p-value to test the hypotheses with a equal to .10, .05, .01, and .001. How much evidence is there that the proportions of homeowners and renters differ? (Round the intermediate calculations to 3 decimal places. Round your z value to 2 decimal and p-value to 3 decimal places.) 0.49 p- value = 0.623 Reject HO at a = 0.1 but not at a = 0.1, 0.05, 0.01 and 0.001 no evidence that p1 and p2 differ. (c) Calculate a 95 percent confidence interval for the difference between the proportions of homeowners and renters who would buy the security system. On the basis of this interval, can we be 95 percent confident that these proportions differ? (Round your answers to confidence interval to 4 decimal places. Negative amounts should be indicated by a minus sign. ) (0.0851) 0.1421 ]: Confidence interval = No
