Identity Theft In a KRC Research poll, 1002 adults were asked if they felt vulnerable to identity theft, and 531 of them said “yes.” Use a 0.05 significance level to test the claim that the majority of adults feel vulnerable to identity theft.

Testing Claims About Proportions. In Exercises 9–32, test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value or critical value(s), conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method unless your instructor specifies otherwise. Use the normal distribution as an approximation to the binomial distribution (as described in Part 1 of this section).
