### Refer to the Buena School District bus data. Select the variable for the number of miles traveled last month.

#### Description

Refer to the Buena School District bus data.a. Select the variable for the number of miles traveled last month. Conduct a test of hypothesis to determine whether the mean number of miles traveled is equal to 840. Use the .01 significance level. Find the p-value and explain what it means.b. Using the maintenance cost variable, conduct a test of hypothesis to determine whether the mean maintenance cost is less than \$500 at the .05 significance level. Determine the p-value and interpret the result.c. Suppose we consider a bus "old" if it is more than eight years old. At the .01 significance level, can we conclude that less than 40% of the buses are old? Report the p-value. I didn't include the data file. I'm asking if you would list the steps I need to take to solve the 3 questions. I want to know how to do it correctly, not just copy answers. Thanks!
