A sample of 340 randomly selected adult Americans were asked this question: “Do you use a remote start for your vehicle during the Winter?” 117 answered “yes.” Based on this, is it reasonable to assume that more than 33% of adult Americans use a remote start during the Winter? Set up the relevant hypotheses, show the sample is appropriate for this test, calculate a test statistic and P-value, decide whether or not to reject the null hypothesis, and put your conclusion in context of the scenario. Round P-value to 4 decimal places and test statistic to 2 decimal places. Use ∝= .05. Hypotheses: Address appropriateness of size: Value of test statistic: ________________________________ P-value: ________________________________ State your conclusion in the context of the problem.
