MY NOTES ASK YOUR TEACHER 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. * 67 (a) Verify that Ex = 438, Ly = 277, Ex? = 32264, Ly? = 12899, Exy = 20365, and r & 0.803. Ex 438 Ey 277 Ex2 32264 Ly2 12899 Exy 20365 |0.803 (b) Use a 5% level of significance to test the claim that p > 0. (Round your answers to two decimal places.) t 2 69 critical t 2 78 Conclusion O Reject the null hypothesis, there is sufficient evidence that p > 0. Reject the null hypothesis, there is insufficient evidence that p > 0. Fail to reject the null hypothesis, there is insufficient evidence that p > 0. O Fail to reject the null hypothesis, there is sufficient evidence that p > 0. (c) Verify that S x 3.1357, a ~ 9.918, b x 0.4966, and x x 73.000. S Enter a number (d) Find the predicted percentage y of successful field goals for a player with x = 67% successful free throws. (Round your answer to two decimal places.) % (e) Find a 90% confidence interval for y when x = 67. (Round your answers to one decimal place.) lower limit upper limit (f) Use a 5% level of significance to test the claim that & > 0. (Round your answers to two decimal places.) critical t Conclusion O Reject the null hypothesis, there is sufficient evidence that B > 0. O Reject the null hypothesis, there is insufficient evidence that B > 0. . Fail to reject the null hypothesis, there is insufficient evidence that B > 0. O Fail to reject the null hypothesis, there is sufficient evidence that B > 0
