Given,
y = -0.83 *x + 26.507
r2=0.443556
Therfore,
r = 0.666
If a man watches 4.5 hours of tv then,
y = (-0.83 * 4.5)+26.507
y = 22.8
The number of sit-ups a person who watches 4.5 hours of TV can do is
22.8

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=ax+b a=-1.179 b=22.006 r2=0.595984 r=-0.772 Use this to predict the number of situps a person who watches 5.5 hours of TV can do (to one decimal place)
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=ax+b a=-0.867 b=23.962 r2=0.702244 r=-0.838 Use this to predict the number of situps a person who watches 9.5 hours of TV can do (to one decimal place)
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=ax+b a=-1.263 b=21.291 r2=0.5776 r=-0.76 Use this to predict the number of situps a person who watches 5 hours of TV can do (to one decimal place)
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=ax+b a=-0.622 b=30.666 r2=0.868624 r=-0.932 Use this to predict the number of situps a person who watches 6.5 hours of TV can do (to one decimal place)
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=ax+b a=-1.193 b=28.861 r2=0.763876 r=-0.874 Use this to predict the number of situps a person who watches 3.5 hours of TV can do (to one decimal place)
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=ax+b a=-0.659 b=32.254 r2=0.499849 r=-0.707 Use this to predict the number of situps a person who watches 11.5 hours of TV can do (to one decimal place)
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=ax+b a=-0.609 b=35.322 r2=0.481636 r=-0.694 Use this to predict the number of situps a person who watches 7.5 hours of TV can do (to one decimal place)
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=ax+b a=-1.026 b=24.441 r2=0.958441 r=-0.979 Use this to predict the number of situps a person who watches 1 hours of TV can do (to one decimal place) Please show work
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=ax+b a=-0.949 b=30.119 r2=0.597529 r=-0.773 Assume the correlation is significant, and use this to predict the number of situps a person who watches 10 hours of TV can do (to one decimal place)
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...
