Question

The amount of fill X put into bottles of a particular brand of apple juice can be described by a normal model with mean E(X) = μ = 28 ounces and standard deviation SD(X) = σ = .85 ounces. What is the median amount of apple juice put into a bottle, that is, what is the amount k such that P(X > k) = P(X < k) = 0.50? Right-click this link standard normal table to open a standard normal table in a separate window or tab. 28 29.

28

29.96

27.15

29.7

28.85

Answer #1

Solve this problem using

Zscore = (X - mean)/ s.d.

As x follow normal distribution

We get k = mean + Zvalue ( s.d.)

We get Z = in this case

Hence k= mean=28

. Filling Bottles. A certain brand of apple juice is supposed to
have 64 oz. of juice. Because the filling machine is not precise,
the exact amount of juice varies from bottle to bottle. The quality
control manager wishes to verify that the mean amount of juice in
each bottle is 64 oz., so she can be sure that the machine is not
over or under filling. She randomly samples 22 bottles of juice and
measures the content. She obtains...

A certain brand of apple juice is supposed to contain 64 ounces
of juice. A random sample of 22 bottles of juice had a mean of
63.96 oz. with a standard deviation of .05 oz. Use a 0.10
significance level to test the claim that the mean amount of juice
in all bottles is different from 64 ounces. a. State the
appropriate null and alternative hypotheses. b. Compute the test
statistic. c. Compute the P-value for this test. d. Show...

A certain brand of apple juice is supposed to have 64 ounces of
juice. The target mean amount of juice is 64.05 ounces. However,
the filling machine is not precise, and the exact amount varies
from bottle to bottle. The quality control manager wishes to verify
that the mean amount in each bottle is 64.05 ounces so that she can
be sure that the machine is not over-filling or under-filling. She

A company's manufacturing process results in wastewater that
contains an amount X (measured in parts per million) of a chemical
pollutant. A "scrubbing" machine removes most of the chemical
pollutant before pumping the wastewater into a nearby lake. The
company must pay a large fine if the treated water contains more
than 80 parts per million of the chemical pollutant, so the company
sets the scrubbing machine to attain an expected chemical pollutant
value E(X) = μ = 75 in...
