Use the expression in the accompanying discussion of sample size to find the size of each sample if you want to estimate the difference between proportions of men and women who own smartphones. Assume that you want 95% confidence that your error is no more than 0.02. A Click the icon to view the discussion of sample size. The sample should include men and women. (Type whole numbers.) Sample size discussion The sample size needed to estimate the difference between two population proportions to within a margin of error E with a confidence level of 1-a can be found by using the following expression: P191 P292 E=Za/2 n1 n2 Replace n, and n2 by n in the preceding formula (assuming that both samples have the same size) and replace each of p,, 9,, P2, and q2 by 0.5 (because their values are not known). Solving for n results in this expression: a/2 n = 2E? Print Done

For the hypothesis test, identify the value used for the population proportion and use the symbol that represents it. (Type an integer or a decimal rounded to two decimal places as needed.)

A sample of 900 computer chips revealed that 46 % of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 50 % of the chips do not fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that do not fail is different from the stated percentage. Find the value of the test statistic. Round your answer to two decimal places. Answer Tables Keypad
