Gun ControlHistorically, the percentage of U.S. residents who support stricter gun control laws has been 52%. A recent Gallup Poll of 1011 people showed 495 in favor of stricter gun control laws. Assume the poll was given to a random sample of people.
You want to test the claim that the proportion of those favoring stricter gun control has changed from 0.52. Perform a hypothesis test, using a significance level of 0.05, by following the steps.
Can you please show me how to do this problem, I am studying for an exam and I have struggled with problems like this one.
Part 1: State the population for this study
Part 2: State your hypothesis in words AND using symbols
Part 3: Tell what kind of test statistic best fits this problem and why
Part 4: List the conditions required for this test and show that all of the conditions are met.
Part 5: Tell the equation for your test statistic, calculate your test statistic (either show the work by hand or tell what you entered into technology and show the output), then give your final answer to two decimal places.
Part 6: Calculate your p-value (either show/explain how to use the table to find your p-value or tell what you entered into technology and show the output), and then give your final answer as a decimal rounded to four decimal places.
Part 7: Find the critical values.
Part 8: Draw the curves for the classical approach and the p-value approach.
Part 9: List the decision rules for the classical approach and the p-value approach. Then make a decision using both rules. Do your answers match?
Part 10: State your conclusion in terms of the original question.
Part 11: Do you think there are any outside variables influencing the data? What could be done to improve the study if it was done again?
