sing the dotplot and the sample mean mileage, is there convincing evidence that the new type of tread improves e mileage of the tire? Yes, because a mean mileage of 51,500 or more occurred only 14 out of 200 times, the mean mileage is statistically significant. There is convincing evidence the new type of tire tread improves mileage of the tire. OYes, because a mean mileage of 51,500 or less occurred 186 out of 200 times, the mean mileage is statistica significant.

Manufacturers of tires report that car tires should be able to last an average of 50,000 miles. A new tire company produces a different type of tread and tests 100 randomly selected tires. This sample of 100 tires lasted an average of 51,500 miles. Assuming the new type of tread does not improve the mileage of the tire, 200 sample means were simulated and displayed on the dotplot. Simulated Tire Mileage H++ ++++ 47,000 48,000 49,000 50,000 51,000 52,000 53,000 Mean mileage Save and Exit Next Submit Unmark this question
