A local brewery sells their beer in 330 ml bottles. On average
the beer is filled with 328.2 ml with a standard deviation of 0.7
ml.
1. Since it is possible to under-fill the bottle but impossible to
fill the bottle with more than 330 ml, the distribution is:
Normal
Symmetrical
Skewed Left
Skewed Right
2. Use this information to answer the following questions, and
round your answers to four decimal places.
a. What is the z-score for a six-pack with an average fill from all
the bottles being 328.7 ml?
b. What is the z-score for a twelve-pack with an average fill from
all the bottles being 328.7 ml?
c. What is the z-score for a twelve-pack with an average fill from
all the bottles being 328 ml?
You are interested in comparing the local brewery to a large chain.
The large chain sells their beer in 330 ml bottles as well. On
average the beer is filled with 328.1 ml with a standard deviation
of 0.6 ml.
3. Let's consider the large chain.
a. What is the z-score for a six-pack from the large chain with an
average fill from all the bottles being 328.7 ml?
b. Are you more likely to see a six-pack from the local brewery or
a six-pack from the large chain with an average fill of 328.7
ml?
Local Brewery
Large Chain
c. Are you more likely to see a twelve-pack from the local brewery
or a twelve-pack from the large chain with an average fill of 328
ml?
Local Brewery
Large Chain
Write smaller number first for both questions below. Round to 2
decimal places.
4. a. At the local brewery the middle 68% of six-packs will have an
average fill between ml and ml.
b. At the large chain brewery the middle 68% of six-packs will have
an average fill between ml and ml.

Beer bottles are filled so that they contain an average of 475 ml of beer in each bottle. Suppose that the amount of beer in a bottle is normally distributed with a standard deviation of 8 ml. [You may find it useful to reference the z table.] a. What is the probability that a randomly selected bottle will have less than 470 ml of beer? (Round intermediate calculations to at least 4 decimal places, “z” value to 2 decimal places,...

A local brewery distributes beer in bottles labeled 24 ounces. A government agency thinks that the brewery is cheating its customers. The agency selects 50 of these bottles, measures their contents, and obtains a sample mean of 23.6 ounces with a standard deviation of 0.8 ounces. Use a 0.01 significance level (α = 0.01) to test the agency's claim that the brewery is cheating its customers (that the average volume of their beers is less than 24 ounces). H0: Ha:...
A local brewery wishes to ensure that an average of 12 ounces of beer is used to fill each bottle. In order to analyze the accuracy of the bottling process, the bottler takes a random sample of 16 bottles with the following results. The data are shown below.
