Question
A consumer advocate examines whether the longevity of car batteries (measured in years) is affected by the brand name (factor A) and whether or not the car is kept in a garage (factor B). Interaction is suspected. Also assume longevity is normally distributed. Using the EXAM2_Battery_Longevity.xlsx data (click here for the data), generate the Excel output for a two-factor ANOVA with interaction. Which of the following answers is correct? O There are significant interactions effects of Brand and Garage-Kept on the longevity of the car batteries. O There is no evidence that being kept in the garage effects the longevity of car batteries. O None of these statements is correct. There is evidence that the brands differ in the longevity of their car batteries.
