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.   Given that Se ≈ 3.668, a ≈ 16.331, b ≈ 0.436, and , use a 5% level of significance to find the P-Value for the test that claims β is greater than zero.
