The mean incubation time for a type of fertilized egg kept at 100.7
The mean incubation time for a type of fertilized egg kept at 100.7°F is 20 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 11 day. (a) What is the probability that a randomly selected fertilized egg hatches in less than 18 days? (b) What is the probability that a randomly selected […]
