Suppose you are interested in measuring the amount of time, on average, it takes you to make your commute to school. You've estimated that the average time is 38.37 minutes with a standard deviation of 6.548 minutes. Assuming that your estimated parameters are correct and the commute time is normally distributed, what is the probability that the average commute time of 10 random days is greater than 37.78 minutes?

You are interested in determining the amount of time (in minutes) you spend each day on the Internet. For seven days, these values are: 51, 24, 16, 88, 63, 28, and 59. Assume that the amount of time you spend on the Internet each day is normally distributed, and develop a 90% confidence interval for the population average amount of time.

A) The Transportation Department determines that in a certain metropolitan area the average one-way commute takes 1 hour 10 minutes (70 minutes). The distribution of commute times is normally distributed with a standard deviation of 8 minutes. If you select a person randomly, what is the probability that his or her commute takes less than 55 minutes? B) Using this same distribution; If you select a person randomly, what is the probability that you find that his or her commute...

Suppose the average commute time of your employees is unknown. The standard deviation of their commute time is estimated as 27.6 minutes. How many employees must be included in a sample to create a 99 percent confidence interval for the average commute time with a confidence interval width of no more than 17 minutes? Note that the correct answer will be evaluated based on the z-values in the summary table in the Teaching Materials section. Remember to round your answer...
