Mathematics

The probability that the amount dispensed per box will have to be increased is 0.0062.

Step-by-step explanation:

Consider the provided information.

Sample of 16 boxes is selected at random.

If the mean for 1 hour is 1 pound and the standard deviation is 0.1

1 Pound = 16 ounces , then 0.1 Pound = 16/10 = 1.6 ounces

Thus: μ = 16 ounces and σ = 1.6 ounces.

Compute the test statistic $z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}$

$z=\frac{15-16}{\frac{1.6}{\sqrt{16}}}$

$z=\frac{-1}{\frac{1.6}{4}}$

$z=\frac{-1}{0.4}$

z=-2.5

By using the table.

P value = P(Z<-250) = 0.0062

Thus, the probability that the amount dispensed per box will have to be increased is 0.0062.
