DATA 2.5- pg-90 2020 New Car Models The dataset Cars2020 contains information for a sample of 110 new car models47 in 2020. There are many variables given for these cars, including model, price, miles per gallon, and weight. One of the variables, QtrMile, shows the time (in seconds) needed for a car to travel one-quarter mile from a standing start.

Question- Braking DistanceData 2.5on page 90 introduces theCars2020dataset with information on 110 new car models in 2020. TheBrakingvariable measures the distance (in feet) it takes the car to stop when travelling at 60 mph on dry pavement.

1. Use technology to find the mean and standard deviation of the braking distances for this sample of car models.
2. Are there any braking distances that are more than two standard deviations away from the mean?
