Using the standard normal curve, the probability or area between z = -1.28 and z = 1.28 is 0.3997.
Standard Normal Curve
The standard normal curve is a type of normal curve with a mean of 0 and a standard deviation of 1, used as a reference in probability and statistics.
Probability
A measure of the likelihood that an event will occur, expressed as a number between 0 and 1 where 0 indicates impossibility and 1 indicates certainty.
Z
A statistical measure used in the context of standard deviations to describe the position of a raw score in relation to the mean of a group of scores.
