Question

An auto parts manufacturer throws out gaskets with weights that are not within 0.06 pound of the mean weight of the batch. The weights (in pounds) of the gaskets in a batch are 0.58, 0.63, 0.65, 0.53, and 0.61. Which gasket(s) should be thrown out?

Answer 1

Answer:

0.53 will not chosen

Step-by-step explanation:

Given weights:

0.58, 0.63, 0.65, 0.53, and 0.61.

Computation:

Mean weight X = [0.58+0.63+0.65+0.53+0.61] / 5

Mean weight X = [3] / 5

Mean weight X = 0.60

Acceptable weight = l x-X l < 0.06

l x-0.60 l < 0.06

So solving inequality

0.54 < x < 0.66

So, 0.53 will not chosen.
