Help answer all three questions! In a random sample of 22 people,

In a random sample of 22 people, the mean commute time to work was 30.3 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 p. What is the margin of error of u? Interpret the results The confidence interval for the population mean u is INED (Round to one decimal place as needed.) The margin of error of u is (Round to one decimal place as needed.) Interpret the results O A. With 95% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval O B. It can be said that 95% of people have a commute time between the bounds of the confidence interval O C. With 95% confidence, it can be said that the commute time is between the bounds of the confidence interval. X More Next 10:10 AM 54 F Sunny (8) 11/11/2021
