Suppose that a simple linear regression model has been fit, and the following information is available:
SSE = 552
n = 21
sx = 27.45
x with bar on top equal 9
A researcher wants to construct a 95% prediction interval for a new observation at the value x = 6. The fitted value at this point is
y with hat on top equal 29.82.
Find the upper bound of the prediction interval, to two decimal places.
