In a random sample of 26 ​people, the mean commute time to workwas 30.7 minutes and the standard deviation was 7.2 minutes. Assumethe population is normally distributed and use a​ t-distribution toconstruct a 80​% confidence interval for the population mean mu.What is the margin of error of mu​? Interpret the results. Theconfidence interval for the population mean mu is(-,-) ​(Round toone decimal place)
The margin of error of mu is___. ​(Round to one decimalplace)
Interpret the results
.A. If a large sample of people are taken approximately 80​% ofthem will have commute times between the bounds of the confidenceinterval.
B. It can be said that 80​% of people have a commute timebetween the bounds of the confidence interval.
C. With 80​% ​confidence, it can be said that the populationmean commute time is between the bounds of the confidenceinterval
D. With 80​% ​confidence, it can be said that the commute timeis between the bounds of the confidence interval. Â
