Describe the Distribution of the Sample Mean-Samples from a Population That Is Not Normal
-The ages of five randomly chosen cars in a parking garage are determined to be $7,9,3,4$, and 6 years old. If we consider this sample of 5 in groups of 3 , how many groups can be formed?

D) 60

Question

Quizplus · Accepted Answer

The number of groups of 3 that can be formed from a sample of 5 is calculated using the combination formula $C(n, k) = \frac{n!}{k!(n-k)!}$, where $n$ is the total number of items (5 cars) and $k$ is the size of each group (3 cars). Thus, $C(5, 3) = \frac{5!}{3!(5-3)!} = \frac{5 \times 4}{2} = 10$.
