Question 10 of 10 Do you prefer e-textbooks over print textbooks? Responses for random samples of 'young students' and 'mature students' are summarized below. Prefer e-textbook Sample Size Young Students 119 280 Mature Students 108 200 Standard Normal Distribution Table a. State the hypotheses for testing if a significant difference exists between the two population proportions. $H_0: p_1 - p_2 = 0$ $H_1: p_1 - p_2 \ne 0$ b. Calculate the test statistic. $z = $ Round to two decimal places if necessary Enter 0 if normal approximation cannot be used c. Determine the critical value(s) and state the rejection region for the null hypothesis at $\alpha = 0.01$. Round to two decimal places if necessary Enter 0 if normal approximation cannot be used d. Conclude whether to reject the null hypothesis or not based on the test statistic. Reject Fail to Reject Cannot Use Normal Approximation Standard Normal Distribution Table a. State the hypotheses for testir population proportions. $H_0: p_1 - p_2 = 0$ $H_1: p_1 - p_2 \ne 0$
