On a given day, 68% of the cows will produce an amount of milk within which of the following ranges? O O A. 5.5 gallons to 6.9 gallons B. 4.8 gallons to 7.6 gallons O O C. 4.1 gallons to 8.3 gallons D. 3.4 gallons to 9.0 gallons PREVIOUS

Answer 1

Given. u = 6.2 o=0.7 Using Empirical (or 68-95-99.7) rule. About 68% of all values fall within 1 standard deviation of the mean. (u-0,4+0)=(6.2-0.7,6.2+0.7) = (5.5,6.9) Approximately 68% of the cows will produce an amount of milk ranges within 5.5 gallons to 6.9 gallons. Correct Answer: Option (A)
