According to a reputable magazine, 32% of people in a certain large country have sleepwalked at least once in their lives. Suppose a random sample of 200 people showed that 46 reported sleepwalking. Carry out a hypothesis test that will test whether the proportion of people who have sleepwalked is 0.32. Use a significance level of 0.05. a. Determine the null and alternative hypotheses. b. Identify the values for ?0 (the proportion stated in null hypothesis), x, and n. c. Determine the test statistic. (Round to two decimal places as needed.) d. Determine the P-value. (Round to three decimal places as needed.) e. What is the conclusion to this test?
