The data in the table represent the weights of various domestic cars and their miles per gallon in the city for the 2008 model year. For these data,
the least-squares regression line is y = - 0.006x + 43.875. A twelfth car weighs 3,425 pounds and gets 13 miles per gallon.
(a) Compute the coefficient of determination of the expanded data set. What effect does the addition of the twelfth car to the data set have on
R?
(b) Is the point corresponding to the twelfth car influential? Is it an outlier?

The result is y = -0.14x+ 38.78. Predict the gas mileage when the vehicle is travelling at 55 miles per hour. Round your answer to one decimal place. Only write a number as your answer.arrow_forwardCompute the least-squares regression line for predicting the 2012 budget from the 2006 budget. Round the slope and y- intercept to at least four decimal places.arrow_forward
- A statistics student is studying if there is a relationship between the price of a used car and the number of miles Using the computer output, what is the equation of the least-squares regression line? it has been driven. She collects data for 20 cars of the ý = -0.181 + 24157.2x same model with different mileage, and determines each car's price using a used car website. The analysis is ý = 24157.2 -0.181x given in the computer output. ý = 2164.1 + 0.024x Predictor Coef SE Coef t-ratio Oŷ = 0.024 + 2164.1x Constant 24157.2 2164.1 2.965 0.046 Mileage -0.181 0.024 5.377 0.000 S 3860.7 R-Sq = 68.0% R-Sq(Adj) = 67.5%arrow_forwardEach month for several months, the average temperature in °C (x) and the number of pounds of steam (y) consumed by a certain chemical plant were measured. The least-squares line computed from the resulting data is y = 245.82 + 1.13x. Predict the number of pounds of steam consumed in a month where the average temperature is 65°C. If two months differ in their average temperatures by 5°C, by how much do you predict the number of pounds of steam consumed to differ?arrow_forwardAn airline has determined that the relationship between the number of passengers (x) on a flight and the total weight (y) (in pounds) of luggage stored in the baggage compartment can be estimated by the least-squares regression equation y = 250 + 27x. Predict the weight of luggage for a flight with 125 passengers.arrow_forward
- the scatter plot displays the number of pretzels students could grab with their dominant hand and their handspan, measured in centimeters. the equation of the line y=-14.7+1.59x is called the least-squares regression line because itarrow_forwardA lab received a new instrument to measure pH. To compare the new instrument to the old lab instrument, 11 samples were measured with both pieces of equipment. Using the data (below), find the least squares equation (x = "pH old" and Y = "pH new") and then predict the value on the new instrument if the old instrument gave a pH of 6.30. Enter your answer using 3 significant digits. pH Old pH New 6.35 6.16 6.01 5.95 6.15 6.05 6 6.01 6.11 6.06 5.93 5.83 5.84 5.81 5.63 5.71 5.63 5.74 6.11 6.1 6.07 6.01arrow_forwardFor a class project, you measure the weight in grams (g) and the tail length in millimeters (mm) of a group of mice. The equation of the least-squares line for predicting tail length from weight is: predicted tail length = 19 + 5 (Weight) By looking at the equation for the regression line, what can you tell about the correlation between weight and tail length is?arrow_forward
