Transcribed Image Text:According to a reputable magazine, 35% of people in a certain large country have sleepwalked at least once in their lives. Suppose a random sample of 300 people showed that 63 reported sleepwalking. The null and alternative hypotheses for a
test that would test whether the proportion of people who have sleepwalked is 0.35 are Ho:p=0.35 and H,: p* 0.35, respectively. The conditions for such a test are satisfied. Use the technology output provided to determine the test statistic and
p-value for the test, and provide a conclusion. Use a significance level of 0.05.
