Answer:
Residual = 4.025
Step-by-step explanation:
To find the residual, you need to subtract the actual value from the estimated value.
Residual = actual - estimated
We know the actual value, which is 82 centimeters. We need to find the estimated value. We do that by plugging in 24.5 into the equation that is give to us. Notice ŷ has a little hat above it? This means estimated value.
ŷ = 62.05 + 0.65x
ŷ = 62.05 + 0.65(24.5)
ŷ = 77.975
Residual = actual - estimated
Residual = 4.025
