At the local college, a study found that students completed an average of

3.4 classes per semester. A sample of 52 students was taken. What is the best point estimate for the average number of classes per semester for all students at the local college?

Solution

Since size of the sample (n=52) is large, we can apply central limit theorem.

Using Central limit theorem, the best point estimate for the average number of classes per semester for all students at the local college is 3.4.
