Identify the null hypothesis, alternative hypothesis, test statistic, conclusion about the nullhypothesis, and final conclusion that addresses the original claim.16) A recent gun control study showed that among 1150 Americans, 718 of them favor stricter gunlaws. Use the critical value method and a significance level of 0.05 to test the claim that 65% ofAmericans favor stricter gun lows.

The number of Americans, n=1150 Number of Americans favor stricter gun lows, x=718 The significance…

What happens to the power of a hypothesis test if the significance level is decreased without changing the sample size? Explain your answer.
A national survey conducted in 2011 among a simplerandom sample of 1507 adults shows that 56% of Americans think the Civil War is still relevant toAmerican politics and political life. Conduct a hypothesis test to determine if these data provide strong evidence that the majority (> 50%)of the Americans think the Civil War is still relevant. Please calculate the test statistic, the P-value,and make a conclusion at a 1% significance level.
Determine the test statistic. Determine the P-value.

Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 1807 people and found that 574 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduced. a) Identify the null and alternative hypotheses? Но: ?

O left-tailed O right-tailed O two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. O We reject the null hypothesis,…
