The confidence interval for the population mean u is ( * * *. ) ( Round to one decimal place as needed . ) The margin of error of His ( Round to one decimal place as needed . ) Interpret the results . O A . With 80% confidence , it can be said that the commute time is between the bounds of the confidence interval . O B. With 80% confidence , it can be said that the population mean commute time is between the bounds of the confidence interval . O C. It can be said that 80% of people have a commute time between the bounds of the confidence interval . O D. If a large sample of people are taken approximately 80% of them will have commute times between the bounds of the confidence interval .In a random sample of 20 people. the mean commute time to work was 34.7 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 80% condence interval for the population mean u, What is the margin of error of p? Interpret the results
