# Question

Return to the regression of y = milk pH on x 5 milk temperature described in the previous exercise.
a. Obtain a 95% prediction interval for a single pH observation to be made when milk temperature = 408C.
b. Calculate a 99% prediction interval for a single pH observation when milk temperature = 358C.
c. When the milk temperature is 608C, would a 99% prediction interval be wider than the intervals of Parts (a) and (b)? You should be able to answer without calculating the interval.
