– Analysis of Variance

Suppose we want to examine the safety of compact cars, midsize cars, and full-size cars. It collects a sample of five for each type of cars. Test, whether the mean pressure applied to the driver’s head during a crash test, is equal for each types of car and tell which type of cars had a significant effect on the accident injuries. Use α = 5%.

Compact cars	midsize cars	full-size cars
625	437	490
675	475	446
712	525	402
716	510	490
680	450	460

Set Null and alternative hypothesis:
Do step by step calculations to determine the calculated F and compare it to the critical f stat.
Set your Decision Rule, interpretation and conclusion.
Apply ANOVA using Excel and check your results.
Apply t-test two-samples assuming equal variances to determine which type of cars had a significant effect on the accident injuries.

Two major automobile manufacturers have produced compact cars with the same size engines. We are interested in determining whether or not there is a significant difference in the MPG (miles per gallon) of the two brands of automobiles. A random sample of eight cars from each manufacturer is selected, and eight drivers are selected to drive each automobile for a specified distance. The following data show the results of the test and if the variance of MPG is the same,...
