Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
Question
Transcribed Image Text:(d) Find and interpret the probability that a randomly selected fertilized egg hatches between 20 and 21 days.
The probability that a randomly selected fertilized egg hatches between 20 and 21 days is
(Round to four decimal places as needed.)
Interpret this probability. Select the correct choice below and fll in the answer box to complete your choice.
O A. If 100 fertilized eggs were randomly selected,
(Round to the nearest integer as needed.)
of them would be expected to hatch between 20 and 21 days.
O B. In every group of 100 fertilized eggs,
(Round to the nearest integer as needed.)
eggs will hatch between 20 and 21 days.
O C. The average proportion of the way to hatching of all eggs fertilized between 20 and 21 days is
(Round to two decimal places as needed.)
(e) Would it be unusual for an egg to hatch in less than 18 days? Why?
The probability of an egg hatching in less than 18 days is so it
be unusual, since the probability is
than 0.05.
(Round to four decimal places as needed.)
