The mean incubation time for a type of fertilized egg kept at a certain temperature is 21 days suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day
Draw a normal model that describes egg incubation times of these fertilized eggs
Choose correct graph
D a c b
D
To draw a normal model that describes the egg incubation times of these fertilized eggs, we need to plot a normal distribution curve. The curve should be centered at the mean incubation time of 21 days and have a standard deviation of 1 day.
The correct answer is option D.
