Chapter 1.3, Problem 14E
Licensed drivers. Table 9 contains the state population and the number of licensed drivers in the state (both in millions) for the most populous states in 2014. The regression model for this data is
where
(A) Draw a
(B) If the population of Michigan in 2014 was about 9.9 million, use the model to estimate
the number of licensed drivers in Michigan in 2014 to the nearest thousand.
(C) If the number of licensed drivers in Georgia in 2014 was about 6.7 million, use the model
to estimate the population of Georgia in 2014 to the nearest thousand.

The data show the number of felony convictions, in hundreds, and the crime rate, in crimes per 100,000, for seven randomly selected states. For the given data, a. determine the correlation coefficient between the number of felony convictions and the crime rate, (b) find the equation of the regression line, (c) approximate what crime rate can we anticipate in a state that has 12 hundred felony convictions.Felony convictions: 11.4, 8.1, 6.7, 3.4, 2.4, 2.3, 0.4Crime rate/ 100,000: 12, 9.5, 10.4, 9, 4.2, 5.5, 3.3
A. a. r = 0.906 b. y = 3.85x + 0.777 c. 47
B. a. r = 0.906 b. y = 0.777x + 3.85 c. 13.2
C. a. r = -0.906 b. y = 0.777x - 3.85 c. 5.5
D. a. r = -0.906 b. y = -0.777x + 3.85 c. 5.5
Refer to the data set: Part a: Make a scatterplot and determine which type of model best fits the data.Part b: Find the regression equation, round to two decimal places if necessary.Part c: Use the equation from Part b to determine y when x = -3.6.
A temperature dataset gives y mean April temperature (Fahrenheit) and x = geographic latitude for 20 U.S. cities. The simple
linear regression equation for the sample is ŷ = 119 - 1.64x.

The cost behavior pattern of the maintenance costs must be determined. The accounting staff has suggested the use of linear regression to derive an equation for maintenance hours and costs. Data regarding the maintenance hours and costs for the last year and the results of the regression analysis follow: Month Maintenance Cost Machine Hours Jan. $ 4,200 480 Feb. 3,000 320 Mar. 3,600 400 Apr. 2,820 300 May 4,350 500 June 2,960 310 July 3,030 320 Aug. 4,470 520 Sept. 4,260 490 Oct. 4,050 470 Nov. 3,300 350 Dec. 3,160 340 Sum $ 43,200 4,800 Average $ 3,600 $ 400 Average cost per hour $ 9.00 a (intercept) $ 684.65 b (coefficient) 7.2884 Standard error of the estimate 34.469 R-squared 0.99724 t-value for b 60.105…arrow_forward
