An environmentalist wants to determine the relationships between the numbers (in thousands) of forest fires over the year and the number (in hundred thousands) of acres burned. The data for 8 recent years are shown.
Forest Fires and Acres Burned
Number of Fires (x) 72 69 58 47 84 62 57 45
Number of Acres Burned (y) 62 42 19 26 51 15 30 15
And here's a scatterplot...
Sect 10-1, 10-2 #14
y = 1.0358x - 31.46
R" = 0.5937
Sect 10-1
14. a) b) e) Find r, and use the PPMC table to determine if you can conclude that there is a significant linear correlation in the data.
Sect 10-2
14. If there is a significant linear correlation in the data, use the regression line to predict the number of acres burned if there are x = 60 fires.
