A public opinion organization wants to know if opinions on gun control laws have changed over time. A poll conducted in 2006 found that 55% of people favored stricter gun laws. A poll conducted in 2018 surveyed 250 people and found that 153 people favored stricter gun laws. Perform a hypothesis test to see if the results of the survey provide evidence that the proportion of people favoring stricter gun laws has changed from 2006 to 2018. For a hypothesis test, what would your hypotheses be? Find the p-value? Regardless of your answer to the previous question, let's say you find the p-value is 0.15. If alpha = 0.05, what is your conclusion? Group of answer choices Reject null hypothesis. We have evidence that the proportion favoring stricter gun laws has changed. Reject null hypothesis. We do not have evidence that the proportion favoring stricter gun laws has changed. Do not reject null hypothesis. We have evidence that the proportion favoring stricter gun laws has changed. Do not reject null hypothesis. We do not have evidence that the proportion favoring stricter gun laws has changed. Regardless of your previous answers, let's say the conclusion you make at the end of the test is that the proportion of people favoring stricter gun laws has changed. In truth, the proportion of people favoring stricter gun laws has actually remained the same. What does this mean? Group of answer choices You made a Type I error. You made a Type II error. You made the correct decision.
