Question
In a random sample of 18 people, the mean commute time to work was 34.3 minutes and the standard deviation was 7.3 minutes. Assume the population is normally
distributed and use a t-distribution to construct a 99% confidence interval for the population mean u. What is the margin of error of u? Interpret the results.
The confidence interval for the population mean p is ( )
ents
(Round to one decimal place as needed.)

ccess
Interpret the results.
uccess
O A. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
see so
O B. It can be said that 99% of people have a commute time between the bounds of the confidence interval.
