In a random sample of 17 people, the mean commute time to work was 30.7 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 95% 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 is _______ .
The margin of error of μ is _______ .
Interpret the results
A. With 96% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
B. It can be said that 95% of people have a commute time between the bounds of the confidence interval
C. If a large sample of people are taken approximately 95% of them will have commute times between the bounds of the confidence interval
D. Wah 95% confidence, it can be said that the commuto time in between the bounds of the confidence interval AM
