------------------------------------------------ About 9% of the population has a particular genetic mutation. If 186 people are randomly selected, find the mean number of people with the genetic mutation in such groups of 186.

The mean number of people with a genetic mutation in a randomly selected group of 186 individuals is calculated by multiplying the probability of the mutation (9%) by the group size, resulting in approximately 16.74.

To find the mean for the number of people with a genetic mutation in a group of 186, we use the concept of probability and statistics. The problem states that about 9% of the population has a particular genetic mutation. To calculate the mean, we can multiply the probability of having the mutation by the total number of people in the group.

Mean = Probability of genetic mutation imes Total number of people

Mean = 0.09 imes 186

Mean = 16.74

Therefore, the mean number of people with the genetic mutation in such groups of 186 is approximately 16.74.
