**Test Results (in days):** 14, 13, 18, 28, 19, 20, 23, 24

#### Questions

**(a)** How many degrees of freedom are present in this study?
\[ \_\_\_\_\_ \]

**(b)** What is the point estimate (in days)?

\[ \_\_\_\_\_ \] days

What is the standard deviation (in days) of the sample? (Round your answer to four decimal places.)

\[ \_\_\_\_\_ \] days

**(c)** What is the 95% confidence interval (in days) for the population mean? (Use a table or SALT. Round your answers to three decimal places.)

\[ ( \_\_\_\_\_ , \_\_\_\_\_ ) \] days

**(d)** Interpret the 95% confidence interval for the population mean.

nstructor-created question Question Help ▼ In a test of the effectiveness of garlic for lowering cholesterol, 81 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 20.8. Use a 0.01 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, critical value, test statistic, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. Ho: H=0 mg/dL O B. Ho: µ>0 mg/dL H: uz0 mg/dL H1: µ0 mg/dL Use the t-table to determine the critical value. (Round to three decimal places as needed.) Determine the test statistic. |(Round to…
Applying the Empirical Rule A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 53 months and a standard deviation of 10 months. Using the Empirical Rule, what is the approximate percentage of cars that remain in service between 23 and 43 months?Do not enter the percent symbol.

z Scores LeBron James, one of the most successful basketball players of all time, has a height of 6 feet 8 inches, or 203 cm. Based on statistics from Data Set 1 “Body Data” in Appendix B, his height converts to the z score of 4.07. How many standard deviations is his height above the mean?
Detecting gypsy moths The gypsy moth is a serious threat to oak and aspen trees. A state agriculture department places traps throughout the state to detect the moths. Each month, an SRS of 50 traps is inspected, the number of moths in each trap is recorded, and the mean number of moths is calculated. Based on years of data, the distribution of moth counts is discrete and strongly skewed with a mean of 0.5 and a standard deviation of 0.7. a. Explain why it is reasonable to use a Normal distribution to approximate the sampling distribution of for SRSS of size 50. b. Estimate the probability that the mean number of moths in a sample of size 50 is greater than or equal to 0.6. c. In a recent month, the mean number of moths in an SRS of size 50 was = 0.6. Based on this result, is there convincing evidence that the moth population is getting larger in this state? Explain your reasoning.
