From previous studies, it is concluded that 13% of people mind if others smoke near a building entrance. A researcher claims it has increased and decides to survey 100 adults. Test the researcher's claim at the a = 0.05 significance level. Preliminary: a. Is it safe to assume that n < 0.05 of all subjects in the population? No Yes b. Verify np(1 - p) 10. Round your answer to one decimal place. np(1 - p) = Test the claim: a. Express the null and alternative hypotheses in symbolic form for this claim. Ho: 7 H.: ? ? b. After surveying 100 adult Americans, the researcher finds that 13 people mind if others smoke near a building entrance. Compute the test statistic. Round to two decimal places. z= c. What is the p-value? Round to 4 decimals. p = d. Make a decision based on a = 0.05 significance level. Reject the null hypothesis. Do not reject the null hypothesis. e. What is the conclusion? There is not sufficient evidence to support the claim that 13% of people mind if others smoke near a building entrance has increased.
