Refer to the Buena School District bus data ( 2012). Select the variable referring to the number ofmiles traveled last month, and then organize these data into a frequency distribution. a. What is a typical amount of miles traveled? What is the range? b. Comment on the shape of the distribution. Are there any outliers in terms of milesdriven? c. Draw a cumulative frequency distribution. Forty percent of the buses were driven fewerthan how many miles? How many buses were driven less than 850 miles? d. Refertothevariablesregardingthebustypeandthenumberofseatsineachbus.Drawa pie chart of each variable and comment on your findings

Refer to the Lincolnville School District bus data. 1. Refer to the maintenance cost variable. The mean maintenance cost for last year is $4,552 with a standard deviation of $2,332. Estimate the number of buses with a maintenace cost of more than $6,000. Compare that with the actual number. Create a frequency distribution of maintenance cost. Is the distribution normally distributed? 2. Refer to the variable on the number of miles driven since the lastm maintenance. The mean is 11,121...

) A public school district is investigating whether to purchase a new school bus to take over the rural-most route in the district. They have two options: A modern, eco-friendly bus complete with seat belts and air conditioning, will have a first cost of $95,000, cost savings (in terms of fuel efficiency and maintenance costs) of $20,000/year the first year, and decreasing by $1000 per year thereafter (so $19,000 the second year, 18,000 the third year, etc…). It’s estimated that...

The Boston public school district has had difficulty maintaining on-time bus service for its students. Suppose the district develops a new bus schedule to help combat chronic lateness on a particularly woeful route. After the schedule adjustment, the first 36 runs were an average of 8 minutes late. As a result, the Boston public school district claimed that the schedule adjustment was an improvement—students were late less than 15 minutes. Assume a population standard deviation for bus arrival time of...
