Question:
Sweetness of orange juice. Refer to the study of the quality of orange juice produced at a juice manufacturing plant, Exercise 11.32
(p. 629). Recall that simple linear regression was used to predict the sweetness index (y) from the amount of pectin (x) in orange juice manufactured during a production run.
a. Give the values of SSE, s2, and s for this regression.
b. Explain why it is difficult to give a practical interpretation to s2.
c. Use the value of s to derive a range within which most
(about 95%) of the errors of prediction of sweetness index fall.
