Question

The mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Complete parts (a) through (e) below. The probability that a randomly selected fertilized egg takes over 26 days to hatch is 0.1587. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice. (Round to the nearest integer as needed.) A. In every group of 100 fertilized eggs, eggs would be expected to hatch in more than 26 days. B. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 26. C. If 100 fertilized eggs were randomly selected, 16 of them would be expected to take more than 26 days to hatch. (d) Find and interpret the probability that a randomly selected fertilized egg hatches between 23 and 25 days. The probability that a randomly selected fertilized egg hatches between 23 and 25 days is .4772. (Round to four decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice. (Round to the nearest integer as needed.) A. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 23 or on day 25. B. In every group of 100 fertilized eggs, eggs would be expected to hatch between 23 and 25 days. C. If 100 fertilized eggs were randomly selected, of them would be expected to hatch between 23 and 25 days.
