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…

Weather-Related Deaths Review Exercise 5 involved weather-related U.S. deaths. Among the 450 deaths included in that exercise, 320 are males. Use a 0.05 significance level to test the claim that among those who die in weather-related deaths, the percentage of males is equal to 50%. Provide an explanation for the results.

The US Department of Energy reported that 48% of homes were heated by natural gas. A random sample of 336 homes in Oregon found that 142 were heated by natural gas. Test the claim that proportion of homes in Oregon that were heated by natural gas is different than what was reported. Use a 10% significance level. Give answer to at least 4 decimal places. What are the correct hypotheses? (Select the correct symbols and use decimal values not percentages.) Based on the hypotheses, compute the following:Test Statistic = p-value =
Consider a drug testing company that provides a test for marijuana usage. Among 266 tested subjects, results from 27 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test results are wrong.
use the math problem uploaded to answer the question. Will you reject or fail to reject the null hypothesis? choose one: a) The P-Value is greater than the level of significance and so we reject the null hypothesis that the variances are equal. At 0.05 level of significance, we conclude that the variance for the first plot is greater than the variance for the second plot. b) The P-Value is greater than the level of significance and so we fail to reject the null hypothesis that the variances are equal. At 0.05 level of significance, we conclude that the variance for the first plot is equal to the variance for the second plot. c) The P-Value is greater than the level of significance and so we reject the null hypothesis that the variances are equal. At 0.05 level of significance, we conclude that the variance for the first plot is equal to the variance for the second plot. d) The P-Value is less than the level of significance and so we fail to reject the null hypothesis…
