15. For a random sample of n = 64, find the probability of a sample mean being less than 24.3 when p = 24 and o = 1.25.

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

To find the probability first we have to determine the z score which is

= 1.92

Now probability is

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered

the correct answer is e. it may be hard at first for the gang members but soon they will break their habits.

the answer is poetry : )
