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 67 64 75 86 73 73 y 42 40 48 51 44 51 Use a 5% level of significance to test the claim that ρ > 0.

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 | 67 | 64 | 75 | 86 | 73 | 73 |
| y | 42 | 40 | 48 | 51 | 44 | 51 |
Use a 5% level of significance to test the claim that ρ > 0. (Round your answers to two decimal places.)
| t = | |
| critical t = |
Find Se, a, b, and x. (Round your answers to four decimal places.)
| Se = | |
| a = | |
| b = | |
| x = |
(d) Find the predicted percentage ŷ of successful field goals for a player with x = 80% successful free throws. (Round your answer to two decimal places.)
