The amount dispensed by a soft-drink dispensing machine has a normal distribution with mean μ and standard deviation 0.191 ounce

nirvana33 [79]

Answer:

The value of mean is $\mu = 15.64$

Step-by-step explanation:

The normal distribution of the soft-drink dispensing machine can be stated statistically like

$X$ ~ $N (\mu ,0.191^2)$

The standard form representation is

$P(X$

Now we need to obtain $\mu$ in such a way that

$P(X>16) = 0.01$

In standard form

Since

$P(Z>16 -\frac{\mu}{0.191} ) = 0.03$

This means

$P(Z$

Now looking at the z-table for probability of 0.99 we obtain 1.88

i.e

$16 - \frac{\mu}{0.191} = 1.88$

Making $\mu\ the \ subject$

$16 - \mu = 1.88 *0.191$

$\mu = 16 -(1.88*0.191)$

$=15.64$
