In a random sample of 23 people, the mean commute time to work was 30.6 minutes and the standard deviation was 7.2 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 muμ? interpret the results.
the confidence interval for the population mean muμ is ( , )
(round to one decimal place as needed.)
the margin of error of μ
(round to one decimal place as needed.)
interpret the results.
a. if a large sample of people are taken approximately 95% of them will have commute times between the bounds of the confidence interval.
b.with 95% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.
c. with 95% confidence, it can be said that the commute time is between the bounds of the confidence interval.
d. it can be said that 95% of people have a commute time between the bounds of the confidence interval.
