A. No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means.
Step-by-step explanation:
No, the student is not right. The central limit theorem says nothing about the histogram of the sample values. It deals only with the distribution of the sample means. The central limit theorem says that if we take a large sample (i.e., a sample of size n > 30) of any distribution with finite mean and standard deviation
, then, the sample average is approximately normally distributed with mean
and variance

8 gorrilas
Explanation:The ratio of monkeys to gorrila = 5:2
This means there are 5 monkeys for every 2 gorrilas
when there are 20 monkeys,
let the number of gorrilas = x
5 monkeys = 2 gorrilas
20 monkeys = x
cross multiply:
5(x) = 20(2)
5x = 40
divide both sides by 5:
5x/5 = 40/5
x = 8
Hence, if there were 20 monkeys, we would have 8 gorrilas.
