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 0.350 0.270 0.340 0.248 0.367 0.269
y 2.8 7.0 4.0 8.6 3.1 11.1
Verify that Σx = 1.844, Σy = 36.6, Σx2 = 0.579554, Σy2 = 279.62, Σxy = 10.4864, and r ≈ -0.896.
