Final answer:
The mean travel distance for the sample of 75 commuters is 16 miles, and the standard deviation is 7 miles.
Step-by-step explanation:
In this question, we are given that the mean distance that commuters in the United States travel each way to work is 16 miles and the standard deviation is 7 miles. We are asked to consider a sample of 75 commuters. To find the mean travel distance for the sample, we would use the same mean as stated in the news report, which is 16 miles. The standard deviation for the sample can also be estimated to be the same as the population standard deviation, which is 7 miles.
Therefore, the mean travel distance for the sample of 75 commuters is 16 miles, and the standard deviation is 7 miles.
