A regression was run to determine if there is a relationship
between hours of TV watched per day (x) and number of situps a
person can do (y).
The results of the regression were:
y = a x + b a = -0.835 b = 31.276 r2 = 0.488601 r = -0.699
Use this to predict the number of situps a person who watches 4
hours of TV can do.
situps = | |
[one decimal accuracy] |
Box 1: Enter your answer as a whole or decimal number. Examples:
3, -4, 5.5
Enter DNE for Does Not Exist, oo for Infinity
y = a x + b a = -0.835 b = 31.276 r2 = 0.488601 r = -0.699
y = a x + b
y = -0.835 * 4 + 31.276
So,
y = 27.936
or
y = 27.9 situps
