Jim is the оwner оf FunPlex, аn indоor plаyground for children. One of the firm's mаin attractions is its giant ball pit the size of a football field that kids can play in. The ball pit consists of red, blue, and green colored plastic balls. Jim believes the most common color ball is red, second most common is blue, and third most common is green. However, due to the massive size of the ball pit he really is not sure. Jim asks his two employees Shawn and Rachel to estimate what percentage of balls in the entire ball pit are red, blue and green: Rachel randomly pulls out 1,000 balls from the pit and records the number of red (330), blue (330) and green (340) balls. Based on this, she estimates that for the entire ball pit = 33% of the balls are red, 33% of the balls are blue, and 34% of the balls are green. Shawn randomly pulls out 100 balls from the pit and records the number of red (40), blue (35), and green (25) balls. Based on this, he estimates that for the entire ball pit = 40% of the balls are red, 35% of the balls are blue, and 25% of the balls are green. Which employee's estimate should the owner Jim believe to be more accurate?
