On average, Americans have lived in 2 places by the time they are 18 years old. Is this average more for college students? The 66 randomly selected college students who answered the survey question had lived in an average of 2.08 places by the time they were 18 years old. The standard deviation for the survey group was 0.5. What can be concluded at the a = 0.10 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: ? v Select an answer v H1: ? v| Select an answer v c. The test statistic ? v = (please show your answer to 3 decimal places.) d.

Hello, I need help answering question 5 please. Thank you very much.
incorrect Using traditional methods, it takes 97 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 110 students and observed that they had a mean of 98 hours. Assume the standard deviation is known to be 7. A level of significance of 0.01 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.

PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC. 1) In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes (before minus after) in their levels of LDL cholesterol (in mg/dL) have a mean of 0.8 and a standard deviation of 1.51. Use a 0.10 significance level to test the claim that with garlic treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic treatment? Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? A. H0: μ=0 mg/dL H1: μ<0 mg/dL B. H0: μ>0 mg/dL H1: μ<0 mg/dL C. H0: μ=0 mg/dL H1: μ≠0 mg/dL D. H0: μ=0 mg/dL H1: μ>0 mg/dL…
You noticed that your baseball team has improved. You want to know if your Dodger team is better than teams in your state on a specific measure. You compare your Dodger team's record in the past month to the average of 30.2. Your team of 11 have an average of 32.55 with a standard deviation of 1.508. Use hypothesis testing to form a conclusion about your Dodgerbteam. If appropriate, estimate the population mean that is represented by this sample with a 95% confidence interval.
*please help me with this problem.I need to get it right to complete my homework.* In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before- after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.9 and a standard deviation of 19.8. Construct a 99% confidence interval estimate of the mean net change in LDL cholesterol after garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol? What is the confidence interval estimate of the population mean muu? _mg/dL < muu< _mg/dL
