- The Ontario Ministry of Transportation is studying the relative safety of compact cars, mid-sized cars, and full size cars. Safety data is collected from a random sample of four cars for each of three car types. Using the data provided below, test whether the mean pressure applied to the driver’s head during a crash test is on average equal for each of the car types. Use a significance level of 1%.

Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of three of the treatments (car types). Test whether the mean pressure applied to the driver’s head during a crash test is equal for each type of car. To answer the question, we can set it up as a hypothesis testing problem and use the data collected to answer it. Complete the following to show how...

Suppose the National Transportation Safety Board (NTSB) wants to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of cars each of the cars types. The data below displays the frontal crash test performance percentages. Test whether there are statistical differences in the frontal crash test performance for each type of car. FYI: High scores on crash performance tests are GOOD. (Higher scores means they passed the test a higher percent of the time.)...

An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.

A highway safety institution conducts experiments in which cars are crashed into a fixed barrier at 40 mph. In the institute's 40-mph offset test, 40% of the total width of each vehicle strikes a barrier on the driver's side. The barrier's deformable face is made of aluminum honeycomb, which makes the forces in the test similar to those involved in a frontal offset crash between two vehicles of the same weight, each going just less than 40 mph. You are...
