The data point open paren 4 comma 43 point 6 close paren is 3.8 units above the trend line. - no response given

The residual of the data point (4,43.6)
is −354.4
.

Answer 1

Compute the predicted y: ŷ = 6.6(4) + 13.4 = 26.4 + 13.4 = 39.8.
Residual = actual − predicted = 43.6 − 39.8 = 3.8.

So the correct conclusion is: the data point (4, 43.6) is 3.8 units above the trend line.
