A second-semester junior at a large high school wants to estimate the number of colleges a senior applies to on average before deciding which school they will attend. The junior randomly selects 18 seniors and asks them how many colleges they applied to and records the number. A 99% confidence interval is calculated to estimate the true mean number of colleges seniors at this school apply to before deciding which college to attend. Check all the true statements that apply. Reducing the confidence level will reduce the margin of error. Increasing the sample size will reduce the margin of error. Increasing the sample size will cost this junior too much money. The junior can lower the standard deviation and that would reduce the margin of error. If they decrease the confidence level, then they are decreasing the level of certainty that they have captured the true mean.
The police department estimated the average speed of cars along boul. St. Jean. With hidden radar, the speed of a random selection of 44 cars was measured. It yielded a sample mean of 53 km per/hr and a sample standard deviation of 5.9 km per/hr. What is the 99.9% confidence interval for the average speed of all cars driving on boul. St. Jean?
A corporation that maintains a large fleet of company cars for the use of its sales staff is interested in the mean distance driven monthly per sales person. The following list gives the monthly distances in miles driven by a random sample of 9 sales persons. 2173 , 2386 , 1945 , 2494 , 2694 , 2084 , 2093 , 2394 , 2668 Send data to calculator Send data to Excel Based on this sample, find a 99% confidence interval for the mean number of miles driven monthly by members of the sales staff, assuming that monthly driving distances are normally distributed. Then find the lower limit and upper limit of the 99% confidence interval.

A sports news station wanted to know whether people who live in the North or the South are bigger sports fans. For its study, 121 randomly selected Southerners were surveyed and found to watch a mean of 4.6 hours of sports per week. In the North, 176 randomly selected people were surveyed and found to watch a mean of 3.2 hours of sports per week. Find a 90% confidence interval for the true difference between the mean numbers of hours of sports watched per week for the two regions if the South has a population standard deviation of 1.6 hours per week and the North has a population standard deviation of 1.4 hours per week. Let Population 1 be people who live in the South and Population 2 be people who live in the North. Round the endpoints of the interval to one decimal place, if necessary.
