What is p (z ≥ 1.20) answer:
What is z score table. 6 rows the z score needs to be calculated before using the z table. These values are of the cumulative distribution. It is a raw value’s relationship to a set of values.
Here, the observed value is above the mean of all the values. We need to standardize his score (i.e. All we’ve done here is translate a normal variable into a standard normal.
Z scores (z value) & z table. You can use this positive z score table to find. Z score is the position of a single data with respect to its mean value which is defined in terms of standard deviation.
The first step is to standardize the given value of 5.0 into a z value (aka, z score):
