Part 1.

Given inequality is = |x-8.2|-1.5≤0

Adding 1.5 to both sides

|x-8.2|-1.5+1.5 ≤ 0+1.5

Simplifying this we get

|x-8.2| ≤ 1.5

Again simplifying we have,

x-8.2 ≤ 1.5 or x-8.2≥ - 1.5

Solving x-8.2 ≤ 1.5 we get, x ≤ 9.7

And

Solving x-8.2≥ - 1.5 we have, x ≥ 6.7

Now combining the ranges we get,

6.7≤ x ≤9.7

Part 2.

This range defines that the babies delivered weigh between 6.7 and 9.7 pounds.

Part 3.

It is unlikely that the next baby born will weigh 6 pounds and 5 ounces as 95% babies weigh more than 6.5 pounds and range lies between 6.7 and 9.7.
