A researcher compares two compounds (1 and 2) used in the manufacture of car tires that are designed to reduce braking distances for SUVs
A researcher compares two compounds (1 and 2) used in the manufacture of car tires that are designed to reduce braking distances for SUVs equipped with the tires. The mean braking distance for SUVs equipped with tires made with compound 1 is 61 feet, with a population standard deviation of 13.0. The mean braking distance for SUVS equipped with tires made with compound 2 is 67 feet, with a population standard deviation of 10.4. Suppose that a sample of 38 braking tests are performed for each compound. Using these results, test the claim that the braking distance for SUVS equipped with tires using compound 1 is shorter than the braking distance when compound 2 is used. Let be the true mean braking distance corresponding to compound 1 and be the true mean braking distance corresponding to compound 2. Use the 0.01 level of significance. Step 4 of 5: Make the decision for the hypothesis test. < Answer 2 Points rev O Reject Null Hypothesis O Fail to Reject Null Hypothesis Tables Keypa Keyboard Shorte
