– 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.

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 ten for each of the treatments (cars types). Using the hypothetical data provided below, test whether the mean pressure applied to the driver’s head during a crash test is equal for each types of car. At the 0.05 significance level, can we conclude that there is a difference in the mean pressures between compact, midsize...

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,...
