Let x be a random variable that represents the percentage of successful free throws a professional basketball player makes in a season. Let y be a random variable that represents the percentage of successful field goals a professional basketball player makes in a season. A random sample of n = 6 professional basketball players gave the following information.

x	86	70	80	76	70	67
y	57	43	46	50	50	41

Given that S_e ≈ 4.075, a ≈ 16.319, b ≈ 0.435, and , ∑x = 449, ∑y = 287, ∑x² = 33,861, and ∑y² = 13,895, find a 99% confidence interval for y when x = 72.
