Explanation / Answer

From given output, regression equation is,

y = ax + b

y = -0.799x + 22.365

We want to predict the number of situps (y) a person who watches 6.5 hours of TV ( x) can do

That is to find, y for x = 6.5 hours

Therefore,

y =( -0.799 * 6.5) + 22.365 = -5.1935 + 22.365 = 17.1715

y = 17.2 ( rounded to one decimal places)

Answer: 17.2
