A company that sells baseball cards claims that 40% of the cards
are rookies, 50% are veterans, and 10% are all stars. Suppose a
random sample of 100 cards has 55 rookies, 40 veterans, and 5
all-stars.

Printed circuit cards are placed in a functional test after
being populated with semiconductor chips. Suppose that there are 8
blue credit cards, 6 red credit cards and 4 blue debit cards in a
box. It is known that color and card type are to be independent
when a card is selected at random from this box.
a) How many red debit cards must be present?
b) Suppose that, 5 cards are randomly selected in a row with
replacement. What...

Please do not use this as an example: For example, let’s
say you had four groups, representing drugs A B C D, with each
group composed of 20 people in each group and you’re measuring
people’s cholesterol level.
In your own words, describe the difference between Among Group
Variation and Within Group Variation. Discuss how you would
evaluate the variation and other methods to ensure that the data is
appropriate to use for the test. Illustrate using a specific
example.

Please, use Excel and show the formulas
The Oliver Cards Company is a card manufacturer. All direct
materials and conversion costs are applied to all of Proball
Trading Cards’ products at an even rate throughout the
manufacturing process.
For August, the beginning work in process inventory for the
Finishing Department was 9,800 units that averaged 65 percent
complete for conversion costs. Materials were done. Ending work in
process inventory was 18,600 units averaged 85 percent complete for
conversion costs. Materials...

It is claimed by a prominent insurance company that exactly 13%
of drivers do not have insurance. The insurance company collects a
sample of 600 drivers and finds that 120 of them do not have
insurance. Test the claim using a level of significance equal to
0.01.

Please use an example to explain when we should use the test.
The example should specify how will you manipulate your IVs and
measure your DV, and how the participants will be tested (e.g.,
same group of participants or different groups) (8 points):
1) Independent sample t test
2) Paired-sample t test
3) One-way ANOVA
4) 2*2 factorial ANOVA
