A random sample of n- 6 professional basketball players gave the following information. 67 75 73 73 y 39 45 48 51 4 51 a) Verify that Ex 438, yy 278, x2 32264, yy2 12988, xy 20432, and r 0.782. Ex 438 yy 278 x2 32264 yy2 12988 yxy 20432 r 782 (b) Use a 5% level of significance to test the claim that p 0. (Use 2 decimal places.) t 2.51 cal t 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. Fail to reject the null hypothesis, there is sufficient evidence that p 0. c) verify that se 3.2274, a 11.595, b 0.4759, and X 73.000 se 3.2274 a 11.595 b 4759 X 73.000 d) Find the predicted percentage of successful field goals for a player with x 77% successful free throws. (Use 2 decimal places.) e) Find a 90% confidence interval for y when x 77, (Use 1 decimal place lower limit 40.6 upper limit 55.8 v Use a 5% level of significance to test the claim that B 0. (Use 2 decimal places critical t Conclusion
