I'LL MARK BRAINLIEST.
In a random sample of 21 people, the mean commute time to work was 32.8 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean mu. What is the margin of error of mu? Interpret the results.
ANSWER THE FOLLOWING:
1. The confidence interval for the population mean mu is ( , ).
2. The margin of error of mu is ...
3. Interpret the results.
A.
With 90% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
B.
With 90% confidence, it can be said that the commute time is between the bounds of the confidence interval.
C.
It can be said that 90% of people have a commute time between the bounds of the confidence interval.
D.
If a large sample of people are taken approximately 90% of them will have commute times between the bounds of the confidence interval.
