The value of the mean is 3 for normal curve C and the value of the mean is 4 for the normal curve D, and for both data standard deviation is the same.
What is a normal distribution?
It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
We have a normal distribution curve shown in the picture.
For the normal curve C:
The value of mean = 3 (draw a vertical line in the middle of the curve)
For the normal curve D:
The value of mean = 4 (draw a vertical line in the middle of the curve)
For both data standard deviation is the same.
Thus, the value of the mean is 3 for normal curve C and the value of the mean is 4 for the normal curve D, and for both data standard deviation is the same.
