**Problem Statement:**

What is the probability of randomly selecting 90 observations from a population whose mean is 100 and whose standard deviation is 15.7, and finding that the mean is between 102 and 105?

---

**Notes:**

* This problem involves calculating the probability using the concepts of sampling distributions and the central limit theorem.
* The solution likely involves calculating the standard error and using the normal distribution to find the desired probability.

This type of question is common in statistics courses, focusing on understanding sampling distributions and the effects of sample size on the mean.
