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 Damage Car Damage SUV into Car ($) ($) Honda CR-V into Honda Civic $1,721 $1,274 Toyota RAV4 into Toyota Corolla $1,434 $2,327 Hyundai Tuscon into Kia Forte $850 $3,223 Volkswagon Tiguan into $2,329 $2,058 Volkswagon Golf Jeep Patriot into Dodge Caliber $1,415 $3,095 Ford Escape into Ford Focus $1,470 $3,386 Nissan Rogue into Nissan Sentra $2,884 $4,560 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 Hd = H1 – Hl2, where My is the population mean cost for the SUV Damage and My is the mean cost for the Car Damage. Ho: Ma Select an answer H:Ha Select an answer v b. What is the significance level? a = c. What is the test statistic? Round to 3 decimal places. d. What is the p-value? Round to 4 decimal places. p= = e. Make a decision. Reject the null Do not reject the null f. What is the conclusion? There is sufficient evidence to support the claim that SUVs sustain less damage than cars in a collision. There is not sufficient evidence to support the claim that SUVs sustain less damage than cars in a collision.
