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.
Σx 1
Σy 2
Σx2 3
Σy2 4
Σxy 5
r 6

the answer is 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.

Σx 1

Σy 2

Σx2 3

Σy2 4

Σxy 5

r 6

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

45
