Question

33) A major textbook publisher has a contract with a printing company. Part of the contract stipulates that no more than 5 percent of the pages should have any type of printing error. Suppose that the company selects a random sample of 400 pages and finds 33 that have an error. If the printer is meeting the standard, what is the probability that a sample would have 33 or more errors? A) 0.1250 B) 0.4986 C) 0.1245 D) 0.0014 34) A population has a proportion equal to 0.30. Calculate the following probabilities with n = 100. Find P(p? ? 0.35). A) 0.6126 B) 0.8621 C) 0.7244 D) 0.7124 35) The general format for a confidence interval is: A) point estimate ± (critical value)(standard error). B) point estimate ± (critical value)(standard deviation) C) point estimate ± z (standard deviation). D) margin of error ± (confidence coefficient) (standard error). 36) In an application to estimate the mean number of miles that downtown employees commute to work roundtrip each day, the following information is given: n = 20 x? = 4.33 s = 3.50 If the desired confidence level is 95 percent, the appropriate critical value is: A) .7826 B) t = 2.093 C) t = 2.086 D) z = 1.96
