Question 1150924: Refer to the Lincolnville School District bus data.
a. Refer to the maintenance cost variable. The mean maintenance cost for last year is $4,552 with a standard deviation of $2332. Estimate the number of buses with a maintenance cost of more than $6,000. Compare that with the actual number. Create a frequency distribution of maintenance cost. Is the distribution normally distributed?
b. Refer to the variable on the number of miles driven since the last maintenance. The mean is 11,121, and the standard deviation is 617 mile. Estimate the number of buses traveling more than 11,500 miles since the last maintenance. Compare that number t the actual value. Create a frequency distribution of miles since maintenance cost. Is the distribution normally distributed?
