A student developed a linear regression model ġ = ao + a1x based on four data points. He found that the resulting linear model is a line of zero slope. He asked you to double check his work. However, the piece of paper he handed you was smudged with food stains and the y value of the last data point was unreadable. Assuming his linear regression work is correct, what is the missing value for y at x = 18? . I 2 3 16 111 22 118 ??
