Solution to the problem
The general expression for a linear model is given by:
Where is the intercept and
the slope
For this case we have a linear model given by the following expression:
Where -3.34 is the intercept and 1.07 the slope. In order to find the best predicted value when X = 91 we just need to replace into the equation the value of 91 and we got this:
On this case is the best predicted value because we have an unbiased estimator.
