To find the answers, we first need to calculate the correlation, slope, and y-intercept using a statistical software or calculator. Once we have these values, we can use them to predict the points scored for a game with 190 rushing yards.
After calculating, the answers are as follows:
Correlation: 0.7916
Slope: 0.0707
Y-intercept: 6.96
Predicted points scored for a game with 190 rushing yards: 20
The data in the table below are the rushing yards and the number of points scored for 8 games played by the 2011 Jacksonville Jaguars.
Rushing Yards
163 112 128 104 108 133 132 84
Points scored
16 3 10 10 13 12 14
Give the answers
What is the correlation between the values, rounded to the nearest hundredth?
What is the slope of the regression line, rounded to the nearest hundredth?
What is the y-intercept, rounded to the nearest hundredth?
What is the predicted points scored for a game with 190 rushing yards, rounded to the nearest whole number?
