The average number of miles people commute per day is 24 miles with standard deviation of 3.5 miles. A researcher claims it is less than that according to his study sample. The study sample had mean of 22.8 miles, with 49 samples.

Step 1
- Null hypothesis (H0): The average commute distance is 24 miles (μ = 24). - Alternative hypothesis (H1): The average commute distance is less than 24 miles (μ < 24). Show more…

30. Going to work: An ABC News report stated that the mean distance that commuters in the United States travel each way to work is 16 miles. Assume the standard deviation is 8 miles. A sample of 75 commuters is chosen. a. What is the probability that the sample mean commute distance is greater than 13 miles?

An ABC News report stated that the mean distance that commuters in the United States travel each way to work is 16 miles. Assume the standard deviation is 8 miles. A sample of 75 commuters was chosen. What is the probability that the sample mean commute distance is greater than 13 miles? What is the probability that the sample mean commute distance is between 18 and 20 miles? Find the 10th percentile of the sample mean. Would it be unusual for the sample mean distance to be greater than 19 miles? Would it be unusual for an individual to have a commute distance greater than 19 miles?
