You are working on logistics with a trucking firm. You have gathered data on miles per gallon of gasoline and the average speed of your cross country trucks.
The following points have been gathered.
| Speed | MPG |
| 60 | 6.2 |
| 55 | 8.3 |
| 70 | 4.5 |
| 62 | 5.1 |
| 59 | 7.2 |
| 62 | 6.0 |
Generate a linear best fit line for this data using speed as X and MPG as Y. The equation for the line should take
the form Y = aX + b
Give the value of "a". Blank 1 (two decimal places)
Give the value of "b". Blank 2 (two decimal places)
What is the R squared value? Blank 3 (two decimal places)
Using Pearson critical values is there a possible correlation between speed and miles per gallon? Blank 4 (yes or no)

Two models of a popular pick-up truck are tested for miles per
gallon (mpg) gasoline consumption. The Pacer model was tested using
a random sample of n1=9 trucks and the sample mean of
27.3 mpg with sample standard deviation s1=6.2 mpg.

regression line
highway mpg = 6.785 + (1.033 × city mpg)
for predicting highway mileage from city mileage.

QUESTION 15
The speed x (in mph) of a car and the related average miles per
gallon y for each speed x are given. Find the quadratic regression
model that best fits the following data: (30, 18), (40, 23), (50,
28), (60, 29), (70, 25)
Round all calculations to two decimal places.
none of these
Y(x) = -.02x2 - 2.80x + 22.00
Y(x) = -.02x2 + 2.00x - 22.00
Y(x) = -.02x 2 + 1.77x - 21.54
