Please help me with this question.
A sample of 30 commuters in the area of a certain city yielded the accompanying commute times, in minutes. Preliminary data
analyses indicate that the t-interval procedure can reasonably be applied. Find and interpret a 99% confidence interval for the
mean commute time of all commuters in the area of the city. (Note: x =26.03 minutes and s = 9.45 minutes."
Click here to view the commute times. Click here to view page 1 of the t-table. Click here to view page 2 of the t-table.
The 99% confidence interval is from minute(s) to minute(s).
(Round to one decimal place as needed.)
Interpret the 99% confidence interval. Select all that apply.
A. 99% of all commuters in the city's area have commute times that are between the interval's bounds.
B. There is a 99% chance that the mean commute time of all commuters in the city's area is between the interval's
bounds.
C. With 99% confidence, the mean commute time of all commuters in the city's area is between the interval's bounds.
D. 99% of all possible random samples of 30 commuters in the city's area have mean commute times that are between the
interval's bounds.
