MY NOTES ASK YOUR TEACHER Let x be a random variable that represents the batting average of a professional baseball player. Let y be a random variable that represents the percentage of strikeouts of a professional baseball player. A random sample of n = 6 professional baseball players gave the following information. X 0.332 0.288 0.340 0.248 0.367 0.269 3.2 7.3 4.0 8.6 3.1 11.1 (a) Verify that Ex = 1.844, Zy = 37.3, Ex2 = 0.577322, Ey? = 286.31, Exy = 10.7812, and /x -0.898. Ex 1.844 Ey |37 3 Ex2 0 577322 Ey2 286.31 Exy 10.7812 r -0.898 (b) Use a 1% level of significance to test the claim that p = 0. (Use 2 decimal places.) t 408 critical t + 4.60 Conclusion O Reject the null hypothesis, there is sufficient evidence that p differs from 0. O Reject the null hypothesis, there is insufficient evidence that p differs from 0. Fail to reject the null hypothesis, there is insufficient evidence that p differs from 0. O Fail to reject the null hypothesis, there is sufficient evidence that p differs from 0. (c) verify that S x 1.6204, a x 26.001, and b & -64.375. S 1 6204 a 26 001 6 -64 375 (d) Find the predicted percentage y of strikeouts for a player with an x = 0.298 batting average. (Use 2 decimal places.) 6.82 % (e) Find a 90% confidence interval for y when x = 0.298. (Use 2 decimal places.) lower limit -13 59 * % upper limit 27 22 * %
