E) find a 99% confidence interval for y when x=0.296. use 2 decimal places. lower limits and upper limits. F) use a 1% level of significance to test the claim. use 2 decimal places. t = and critical t=

CD webassign.net/w Student/Assignment-Responses/submit?dep=25 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 0.324 0.310 0.340 0.248 0.367 0.269 3.5 4.0 8.6 11.1 (a) Verify that Ex = 1.858, Ey = 37.4, Ex2 = 0.58523, Ey? = 285.44, Exy = 10.9514, and r x -0.877. W Ex2 Exy (b) Use a 1% level of significance to test the claim that p # 0. (Use 2 decimal places.) critical t + 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 1.7379, a > 26.005, and b x -63.848. (d) Find the predicted percentage y of strikeouts for a player with an x = 0.296 batting average. (Use 2 decimal places.)
