Statistics
In a random sample of 24 people the mean commute time to work was 33 5 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 What is the margin of error of Interpret the results The confidence interval for the population mean 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 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 It can be said that 95 of people have a commute time 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 With 95 confidence it can be said that the population mean commute time is between the bounds of the confidence interval
