Question

if a family has 7 children, what is the interval within which the "number of children they have really falls"

Answer 1

Explanation:

If a family has 7 children, what is the interval within which "the number of children they have" really falls.

Now, number of children is a discrete variable, not a continuous one.

You are sure that the family has 7 children because the question states that.

The true interval within which the number of children they have falls is (0 - 8)
