The lengths of nails produced in a factory are normally distributed with a mean of 4.91 centimeters and a standard deviation of 0.05 centimeters. find the two lengths that separate the top 4% and the bottom 4%. these lengths could serve as limits used to identify which nails should be rejected. round your answer to the nearest hundredth, if necessary.

Step-by-step explanation:

When y varies directly with x

y=kx x=20 y=-8

k=y/x

k=-8/20

k=-0.4

now when x=-4 find y

y=kx

y=-0.4*-4

y=1.6
