Question

The mean incubation time for a type of fertilized egg kept at a certain temperature is 20 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Complete parts​ (a) through​ (e) below. ​(a) Draw a normal model that describes egg incubation times of these fertilized eggs. Choose the correct graph below. Click here to view graph b.LOADING...

The probability that a randomly selected fertilized egg hatches in less than 18 days is . 1. ​(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, . 1 of them would be expected to hatch in less than 18 days. B. If 100 fertilized eggs were randomly​ selected, exactly nothing would be expected to hatch on day 18. C. In every group of 100 fertilized​ eggs, nothing eggs would be expected to hatch in less than 18 days. ​(c) Find and interpret the probability that a randomly selected fertilized egg takes over 22 days to hatch. The probability that a randomly selected fertilized egg takes over 22 days to hatch is nothing. ​(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 nothing would be expected to hatch on day 22. B. If 100 fertilized eggs were randomly​ selected, nothing of them would be expected to take more than 22 days to hatch. C. In every group of 100 fertilized​ eggs, nothing eggs would be expected to hatch in more than 22 days. ​(d) Find and interpret the probability that a randomly selected fertilized egg hatches between 19 and 20 days. The probability that a randomly selected fertilized egg hatches between 19 and 20 days is nothing. ​(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, nothing eggs would be expected to hatch between 19 and 20 days. B. If 100 fertilized eggs were randomly​ selected, nothing of them would be expected to hatch between 19 and 20 days. C. If 100 fertilized eggs were randomly​ selected, exactly nothing would be expected to hatch on day 19 or on day 20. ​(e) Would it be unusual for an egg to hatch in less than 17 ​days? Why? The probability of an egg hatching in less than 17 days is nothing​, so it ▼ would not would be​ unusual, since the probability is ▼ less greater than 0.05..
