An experiment is conducted in which 60 participants each fill out a personality test, but not according to the way the participants see themselves. Instead, 15 are randomly assigned to fill it out...

Solution:
Z statistic are different from T statistic but both are used to find the Probability of getting a
sample.
Sampling distribution is done on the basis of sampling space.
The sample mean is denoted by X

Here, sample size n = 60.
Finding the mean
The mean is found by adding all the observations...
