In a random sample of 23 people, the mean commute time to work was 32 7 minutes and the standard deviation was 7 2 minutes Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean u What is the margin of error of p? Interpret the results The confidence interval for the population mean p is (D (Round to one decimal place as needed ) The margin of error of u is (Round to one decimal place as needed ) Interpret the results View by O A. With 90% 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 90% of people have a commute time between the bounds of the confidence interval. O C. With 90% confidence, it can be said that the commute time is between the bounds of the confidence interval O D. If a large sample of people are taken approximately 90% of them will have commute times between the bounds of the confidence interval
