This test: 21 point(s) possible Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion at the given level of significance using the given sample statistics Claim: ; Sample statistics: Use a t-test to test the claim about the population mean at the given level of significance using the given sample statistics. Assume the population is normally distributed Claim. Sample statistics What are the null and alternative hypotheses? Choose the correct answer below. What is the value of the standardized test statistic? The standardized test statistic is (Round to two decimal places as needed) What is the P -value of the test statistic? P-value (Round to three decimal places as needed.) Decide whether to reject or fail to reject the null hypothesis. A. Fail to reject . There is enough evidence to support the claim. B. Reject . There is not enough evidence to support the claim. C. Fail to reject . There is not enough evidence to support the claim. D. Reject . There is enough evidence to support the claim. Use a t-test to test the claim about the population mean at the given level of significance using the given sample statistics. Assume the population is normally distributed. Claim Sample statistics: What are the null and alternative hypotheses? Choose the correct answer below. Use a -test to test the claim about the population mean at the given level of significance using the given sample statistics. Assume the population is normally distributed. Claim Sample statistics What are the null and altemative hypotheses? Choose the correct answer below (b) Construct and interpret a confidence interval for the population proportion of patients who receive the drug and report a headache as a side effect While the bounds of the confidence interval can be calculated by hand, for this exercise, use technology. Use technology to construct a confidence interval for p with , and . The confidence interval is ( ). (Round to three decimal places as needed.) In a random sample of 20 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a confidence interval for the population mean . What is the margin of error of ? Interpret the results The confidence interval for the population mean is ( 21 point(s) possible (Round to one decimal place as needed ) The margin of error of is (Round to one decimal place as needed.) Interpret the results A. With confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. B. If a large sample of people are taken approximately of them will have commute times between the bounds of the confidence interval C. It can be said that of people have a commute time between the bounds of the confidence interval dom sample of 20 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to onfidence interval for the population mean is confidence interval for the population mean . What is the margin of error of ? Interpret the results In a random sample of 20 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use at-distribution to construct a confidence interval for the population mean . What is the margin of error of ? Interpret the results. The confidence interval for the population mean is (Round to one decimal place as needed.) For each scenario listed on the left, determine whether the scenario represents an Independent Samples or Matched pairs situation by placing the appropriate letter in the box provided. - Comparing pain levels of a group receiving a placebo to a group receiving a - Comparing the number of speeding tickets received by men to the number received by women - Comparing pre-test scores before training to post-test scores after treatment with magnetic therapy a. Matched Pairs b. Independent Samples
