Question
Please I need the right answer to b, c, and d.
Transcribed Image Text:It is a common belief that SUVs are safer than cars. In a collision, does an SUV sustain less damage (cost of
repair) than a car?
SUV into Car
Honda CR-V into Honda Civic
Toyota RAV4 into Toyota Corolla
Hyundai Tuscon into Kia Forte
Volkswagon Tiguan into
Volkswagon Golf
Jeep Patriot into Dodge Caliber
Ford Escape into Ford Focus
Nissan Rogue into Nissan Sentra
Test the claim above at the a = 0.1 level of significance. Note: A normal probability plot of difference in
car damages between SUVs and other cars indicates the population could be normal and a boxplot
indicated no outliers.

a. Express the null and alternative hypotheses in symbolic form for this claim. Assume μ = μl μ2,
where μ₁ is the population mean cost for the SUV Damage and µ2 is the mean cost for the Car
Damage.
