In a random sample of 17 people, the mean commute time to work was 31.2 minutes and the standard deviation was 7.1 minutes. Assume the population is nomally distributed and use a t-distribution to construct a 80% confidence interval for the population mean p. What is the margin of error of u? Interpret the results. Main Menu The confidence interval for the population meanu is ( | D. (Round to one decimal place as needed.) The margin of error of u is |. (Round to one decimal place as needed.) Interpret the results. O A. If a large sample of people are taken approximately 80% of them will have commute times between the bounds of the confidence interval. O B. It can be said that 80% of people have a commute time between the bounds of the confidence interval. O C. With 80% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. O D. With 80% confidence, it can be said that the commute time is between the bounds of the confidence interval.

Transcribed Image Text:In a random sample of 17 people, the mean commute time to work was 31.2 minutes and the standard deviation was 7.1 minutes. Assume the population is
normally distributed and use a t-distribution to construct a 80% confidence interval for the population mean p. What is the margin of error of p? Interpret the
results.
