Solve and answer. The incubation time for Rhode Island Red chicks is normally distributed with a mean of 21 days and a standard deviation of approximately 1 day [based on information from World Book Encyclopedia). If 1000 eggs are being incubated, how many chicks do we expect will hatch: 1. in 20 to 23 days? 2. In 19 to 24 days? 3. In 20 days or fewer? 4. In more than 20 days? 5. In less than 20 days and more than 23 days? (Assume all eggs eventually hatch] Example 3. In Matina Aplaya, it was observed that the incubation period of sea turtles is normally distributed with a mean of 60 days and a standard deviation of approximately 2 days. If 500 eggs are being incubated, how many turtles do we expect will hatch a. in 56 to 60 days? b. in 58 to 62 days? c. in 60 days or fewer? d. in 58 to 66 days? (Assume all eggs eventually hatch) Solutions: a. In 56 to 60 days. 13.5% + 34% = 47.5% 47.5% of 500 eggs will hatch, then 500 (0.475) = 237.5 or approximately 238 eggs will hatch. b. In 58 to 62 days. 34% + 34% = 68% 68% of 500 eggs will hatch, then 500(0.68) = 340 eggs will hatch.c. In 60 days or fewer. 0.15% + 2.35% + 13.5% + 34% = 50% 50% OF 500 eggs will hatch, then 500(0.50) = 250 eggs will hatch. d. In 58 to 66 days. 34% + 34% + 13.5% + 2.35% = 83.85% 83.85% of 500 eggs will hatch. 500(0.8385) = 419.25 or approximately 419 eggs will hatch
