Question

Value of standard deviation from standard normal distribution curve

Answer 1

Answer:

The Standard Normal Distribution has a fixed set of values. The mean, mode and median are all 0. The standard deviation is 1. A (non standard) Normal Distribution will have the same mean and standard deviation as the sample for which it was inferred.

Step-by-step explanation:

In this case, because the mean is zero and the standard deviation is 1, the Z value is the number of standard deviation units away from the mean, and the area is the probability of observing a value less than that particular Z value. Note also that the table shows probabilities to two decimal places of Z
