Automobile fuel efficiency is often measured in miles that the car can be driven per gallon of fuel (highway mpg). Suppose we have a collection of cars. We measure their weights and fuel efficiencies, and generate the following scatterplot. HIGHWAY 40 35 30 25 2500 3000 4000 3500 WEIGHT 25 2500 3000 4000 3500 WEIGHT Which equation is a reasonable description of the least squares regression line for the predicted highway mpg? O predicted highway mpg - 52.3 -0.0067 (weight)...

Problem 1 (18 points) Suppose the distribution of fuel efficiency (miles per gallon (mpg) in highway driving) for a sample of cars has a mound-shaped and symmetric distribution with mean x =38 and standard deviation s = 10 points. Illustrate your answers with graphs. a. Calculate the percent of cars whose fuel efficiency is less than 48 mpg. b. Calculate the percent of scores that are between 28 and 68 mpg. c. Calculate the 16th percentile of the data.

The fuel efficiency in miles per gallon of all BMW 320i’s is approximately normally distributed with a mean of 25 and a standard deviation of 2. A dealer receives a shipment of a random sample of 320i’s (random with respect to mpg) from the factory. Hint: look at the sample sizes and think about which tables you’d need to use for these problems. (a) Find the probability that average fuel efficiency is less than 24 mpg if the dealer receives...

Based on tests of the Chevrolet Cobalt, engineers have found that the miles per gallon in highway driving are normally distributed, with a mean of 32 miles per gallon and a standard deviation of 3.5 miles per gallon. a) If 25 cobalts are randomly selected, how many will have less than 30 miles per gallon? b) How many miles per gallon determine the 3rd quartile? c) 20 cobalts are randomly selecred and the miles per gallon for each car are...
