A corporation that maintains a large fleet of company cars for the use of its sales staff is interested in the mean distance driven monthly per salesperson. The following list gives the monthly distances in miles driven by a random sample of 9 salespeople. 2244, 2387, 2567, 2425, 2223, 2611, 2061, 2683, 2335 Send data to calculator Based on this sample, find a 99% confidence interval for the mean number of miles driven monthly by members of the sales staff, assuming that monthly driving distances are normally distributed. Give the lower limit and upper limit of the 99% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: Upper limit: X S

Question
**Transcription for Educational Website:** --- A corporation that maintains a large fleet of company cars for the use of its sales staff is interested in the mean distance driven monthly per salesperson. The following list gives the monthly distances in miles driven by a random sample of 9 salespeople. - 2244, 2387, 2567, 2425, 2223, 2611, 2061, 2683, 2335 <button>Send data to calculator</button> Based on this sample, find a 99% confidence interval for the mean number of miles driven monthly by members of the sales staff, assuming that monthly driving distances are normally distributed. Give the lower limit and upper limit of the 99% confidence interval. **Instructions:** Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a <a href="list_of_formulas">list of formulas</a>.) - **Lower limit:** [ ] - **Upper limit:** [ ] <button>X</button> <button>Reset</button> <button>Submit Assignment</button> --- **Explanation of Elements:** - The list of numbers represents monthly distances driven by salespeople. These numbers will be used to calculate the 99% confidence interval for the mean monthly distance. - The "Send data to calculator" button likely allows users to input the data directly into a calculator tool for computation. - Input fields are available for users to enter the calculated lower and upper limits of the confidence interval. - There are buttons to perform actions such as clearing input or submitting the assignment. - An additional link provides access to formulas that may assist in the calculations.
