To find the mean number of children in the sample who wear glasses, we need to multiply the percentage of children who wear glasses by the total number of children in the sample.

First, we calculate the number of children who wear glasses in the sample. Since 25% of children wear glasses in the elementary school, we can convert it to a decimal by dividing it by 100: 25/100 = 0.25.

Next, we multiply the decimal by the total number of children in the sample: 0.25 * 64 = 16.

Therefore, in a random sample of 64 children, the mean number of children who wear glasses is 16.
