3. Refer to the Lincolnville School District bus data.
a. Select the variable for the number of miles traveled
last month. Conduct a hypothesis test to determine
whether the mean miles traveled last month equals
10,000. Use the .01 significance level. Find the p-
value and explain what it means.
b. A study of school bus fleets reports that the average
per bus maintenance cost is $4,000 per year. Using
the maintenance cost variable, conduct a hypothesis
test to determine whether the mean maintenance
cost for Lincolnville's bus fleet is more than $4,000
at the .05 significance level. Determine the p-value
and report the results.
