In an elementary school, 25% of children wear glasses. Suppose that a random sample of 64 children is selected. Find the mean number of children in the sample who wear glasses. Round your answer to the nearest integer.
See previous post.
To find the mean number of children who wear glasses in the sample, you need to multiply the total number of children in the sample by the percentage of children who wear glasses.
First, calculate the number of children in the sample who wear glasses. This can be done by multiplying the percentage (25%) by the total number of children in the sample (64):
(25/100) * 64 = 16
Therefore, the mean number of children in the sample who wear glasses is 16.
