21 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.1 minutes
In a random sample of
style=”color:rgb(0,0,0);”>21 people, the mean commute time to work was 34.7 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 99% confidence interval for the population mean μ. What is the margin of error of μ? Interpret the results.
The confidence interval for the population mean μ?
(Round to one decimal place as needed.)
The margin of error of μ?
.
Interpret the results.
A.
It can be said that 99% of people have a commute time between the bounds of the confidence interval.
B.
If a large sample of people are taken approximately 99% of them will have commute times between the bounds of the confidence interval.
C.
With 99% confidence, it can be said that the commute time is between the bounds of the confidence interval.
D.
With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
