The mean incubation time for a type of fertilized egg kept at a certain temperature is 22 days. Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. Complete parts (a) through (e) below. (b) Find and interpret the probability that a randomly selected fertilized egg hatches in less than 20 days. The probability that a randomly selected fertilized egg hatches in less than 20 days is (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.) O A. In every group of 100 fertilized eggs, eggs would be expected to hatch in less than 20 days. O B. If 100 fertilized eggs were randomly selected, of them would be expected to hatch in less than 20 days. O C. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 20. (c) Find and interpret the probability that a randomly selected fertilized egg takes over 24 days to hatch. The probability that a randomly selected fertilized egg takes over 24 days to hatch is (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.) O A. If 100 fertilized eggs were randomly selected, of them would be expected to take more than 24 days to hatch. O B. In every group 100 fertilized eggs, eggs would expected to hatch in more than 24 days. O C. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 24. (d) Find and interpret the probability that a randomly selected fertilized egg hatches between 21 and 22 days. The probability that a randomly selected fertilized egg hatches between 21 and 22 days is (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.) O A. If 100 fertilized eggs were randomly selected, exactly would be expected to hatch on day 21 or on day 22. O B. If 100 fertilized eggs were randomly selected, of them would be expected to hatch between 21 and 22 days. O C. In every group of 100 fertilized eggs, eggs would be expected to hatch between 21 and 22 days. (e) Would it be unusual for an egg to hatch in less than 19 days? Why? The probability of an egg hatching in less than 19 days is soit would be unusual, since the probability is less than 0.05.

Assume that women's weights are normally distributed with a mean given by μ=143 lb and a standard deviation given by 29 lb.(a)  If 1 woman is randomly selected, find the probabity that her weight is between 113 lb and 172 lb(b)  If 3 women are randomly selected, find the probability that they have a mean weight between 113 lb and 172 lb(c)  If 73 women are randomly selected, find the probability that they have a mean weight between 113 lb and 172 lb

The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.6 minutes and a standard deviation of 2.8 minutes. Assume that the distribution of taxi and takeoff times is approximately normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that they take off one at a time on a given runway. USE SALT (a) What is the probability that for 37 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (Round your answer to four decimal places.) 0.5432 (b) What is the probability that for 37 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (Round your answer to four decimal places.) (c) What is the probability that for 37 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes? (Round your answer to four decimal places.)

The migratory habits of zebra in the savanna are normally distributed with a mean of 238 days and a standard deviation of 13 days. Find the probability a single zebra will migrate in less than 220 days.

The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.1 years. A CD player is guaranteed for three years. We are interested in the length of time a CD player lasts. Find the probability that a CD player will break down during the guarantee period.
