if yhat=74.80+19.72x
Then what can we say about E(y)= Bo + B1x?
1. All statements are true
2. A plot of predicted yhat values and x values would NOT result in a straight line
3. Ahe appraised value of y and x for the entire population of houses would fall in a straight line
4. A plot of mean appraised value of E(y) and x for entire population would be in a straight line
