Answer:
19
Step-by-step explanation:
From the question we have been given this data
y=ax+b
a=−1.077
b=30.98
r2=0.744769
r=−0.863
Where
X = number of situps
Y = number of hours spent watching tv
We have x = 11
Inputting this into the formula we have
Y = (-1.077)(11) + 30.98
Y = −11.847 + 30.98
Y = 19.133
Which is approximately 19
Therefore we conclude that a person who watches TV for 11 hours can do 19 situps.
