Homework 13: Problem 1 Previous Problem Problem List Next Problem (1 point) Physicians at a clinic gave what they thought were drugs to 1000 asthma, ulcer, and herpes patients. Although the doctors later learned that the drugs were really placebos, about 54% of the patients reported an improved condition. Assume that if the placebo is ineffective, the probability of a patients condition improving is 0.5. For the hypotheses that the proportion of improving is less than or equal to 0.5 against the hypothesis that it is greater than 0.5, find the approximate pvalue. p value = Homework 13: Problem 2 Previous Problem Problem List Next Problem (1 point) Suppose that we are to conduct the following hypothesis test: H0 I p = 0.52 Sampling lead to a test statistic of 20 = 2.29 The pValue is For a = 0.05, what would be the decision for the hypothesis test? A. Do Not Reject H1 . B. Reject H 0. C. Do Not Reject H 0. D. Reject H1 . Homework 13: Problem 3 Previous Problem Problem List Next Problem (1 point) A sun/ey of 1565 people who took trips revealed that 135 of them included a visit to a theme park. Based on those survery results, a management consultant claims that less than 10 % of trips include a theme park visit. Test this claim using the a = 0.01 significance level. The test statistic is The pvalue is approximately The conclusion is A. There is sufficient evidence to support the claim that less than 10 % of trips include a theme park visit. B. There is not sufficient evidence to support the claim that less than 10 % of trips include a theme park visit
