Standard deviation is just the square root of variance. By taking the square root of the variance, we get our measure back into the interpretable units of the data. In our NBA example, the variance was 13.6 inches squared, so the sample standard deviation would be 13.6 ≈ \sqrt{13.6} \approx 13.6 ≈ 3.69 inches. Because we measure standard ...

P-Value will be –. P-Value = P (z ≥ 2.09) We have to look at the value of 2.09 in the Z table. So, we have to look at -2.0 in the z column and the value in the 0.09 column. Since the normal distribution is symmetrical, the area to the right of the curve is equal to that on the left. So, we get the P-Value as 0.0183.
