Answer:
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
