In a Company Security Institute survey of computer crime, 7 of a sample of 163 reported that unauthorized uses of business websites came from inside the company. Let p represent the true portion of unauthorized uses of business websites in 2008 that came from inside the company. (a) Calculate a point estimate for p. (b) Set up the null and alternative hypothesis to test whether the value of p differs from 0.07. (c) Calculate the test statistic for the test in part (b). (d) Find the rejection region for the test if = 0.05. (e) Use the results of parts (c) and (d) to make the appropriate conclusion. (f) Find the P-value of the test and confirm that the conclusion based on the p-value agrees with the conclusion in part (e).
