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 for each of the car types. Using the data provided below

Pressure Car Type
643 Compact
655 Compact
702 Compact
469 MidSize
427 MidSize
525 MidSize
484 FullSize
456 FullSize
402 FullSize

Test, using Mood’s Median Test, whether the median pressure applied to the driver’s head during a crash test is equal for each types of car. Use α = 5%. Show the appropriate output from Minitab to support your claim and state the significance level you used.

4) The National Transportation Safety Board (NTSB) wanted to examine the safety of three different car types, as measured by head crash test percentages. Cars were classified into three groups: compact (M = , SS = ), midsized (M = , SS = ), and full-size (M = , SS = ). A one-way ANOVA was conducted and determine that there was a statistically significant (or no significant) difference between safety and type of car, F( ___, _____) = _________.

A business consultant for the National Transportation Safety Board (NTSB), collected data on the safety of hybrid automobiles traveling at 30, 40 and 50 miles per hour.  She randomly assigned the same hybrid model to each condition and collected data on the pressure applied to the driver’s head during a crash into a wall at each speed. What is the independent variable? Dependent variable? Is she able to make cause and effect statements about the cars the head pressure? Explain. ...
