Refer to Exercise 2, where we are attempting to link a company’s annual R & D Budget (x) to the number of patents granted to researchers at the company (y). The estimated regression equation turned out to be yˆ = 3.5 + 1.0x. Show the 90% prediction interval for the number of patents granted at a particular company with an annual R & D budget of $11 million.
