The first step is to standardize the given value of 5.0 into a z value (aka, z score):
What is z score table. Z scores (z value) is the number of standard deviations a score or a value (x) away from the mean. Z scores (z value) & z table. It is a raw value’s relationship to a set of values.
All we’ve done here is translate a normal variable into a standard normal. Here, the observed value is above the mean of all the values. What is p (z ≥ 1.20) answer:
The z score is used to. Z score is the position of a single data with respect to its mean value which is defined in terms of standard deviation. Z score of a value defines.
These values are of the cumulative distribution.
