the population mean μ. What is the margin of error of µ? Interpret the results.
The confidence interval for the population mean μ is
(Round to one decimal place as needed.)
The margin of error of u is
(Round to one decimal place as needed.)
Interpret the results.
HD.
A. With 99% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
