Question

Spiral Review Find the range of allowable values based on an expected mass of 250 grams for which values are allowed to vary by 5%.

Answer 1

Given:

An expected mass of 250 grams

It is allowed to vary by 5%

The variation may be increase or decrease

We will find 5% of the given mass

So,

$5\%of250=0.05\times250=12.5\text{ grams}$

So, the range will be from (250 - 12.5) to (250 + 12.5 )

if the allowable value = x

So, the range will be:

$237.5\le x\le262.5$
