Question
In a random sample of eleven people, the mean driving distance to work was 25.9 miles and the standard deviation was 7.2 miles. Assume the population is normally distributed. Find the margin of error and construct a 95% confidence interval for the population mean µ. Interpret the results. -.. Identify the margin of error. (Rou s needed.) Con terval for the population mean. miles per hour (Rou Is needed.) square miles ! correct choice below and fill in the answer box to complete your choice. Do not round.) Inter (Туpр miles 6 of the population has a driving distance to work (in miles) that is between the interval's endpoints. OB. % of all random samples of eleven people from the population will have a mean driving distance to work (in miles) that is between the interval's endpoints. C. With % confidence, it can be said that most driving distances to work (in miles) in the population are between the interval's endpoints. D. With % confidence, it can be said that the population mean driving distance to work (in miles) is between the interval's endpoints.
