Question

Mars Inc. claims that they produce M&Ms with the following
distributions:

Brown | 30% | Red | 20% | Yellow | 20% |

Orange | 10% | Green | 10% | Blue | 10% |

A bag of M&Ms was randomly selected from the grocery store
shelf, and the color counts were:

Brown | 25 | Red | 23 | Yellow | 21 |

Orange | 13 | Green | 15 | Blue | 14 |

Using the χ^{2} goodness of fit test (α = 0.10) to
determine if the proportion of M&Ms is what is claimed. Select
the [p-value, Decision to Reject (RH_{0}) or Failure to
Reject (FRH_{0})].

a) [p-value = 0.535, FRH_{0}]

b) [p-value = 0.232, RH_{0}]

c) [p-value = 0.465, FRH_{0}]

d) [p-value = 0.465, RH_{0}]

e) [p-value = 0.535, RH_{0}]

f) None of the above

M&Ms are multicolored candies in a bag with six colors:
Brown, Blue, Red, Yellow, Green and Orange. Mars now claims that
all six colors are equally likely. In an attempt to reject the
claim, an 8-oz bag of M&Ms was purchased and the colors
counted. The results of the count are below. Does this sample
contradict Mars’ claim when α = 0.10? Brown Blue Red Yellow Green

According to Mars Inc., the distribution of colors of the
M&M candies is Brown- 13 Yellow- 14 Red- 13 Blue- 24 Orange- 20
Green-. 16.Several bags were randomly chosen and the percentages of
each color were found to be as follows: Brown – 15.3%, Yellow
–18.1%, Red – 11.7%, Blue – 19.8%, Orange – 22.6%, and Green –
12.5%. According to this sample, does it appear that the
distribution of colors does not fit what’s expected, according to
the manufacturer’s...

MARS claims that Skittles candies should be comprised of 30%
purple, 10% orange, and 20% should be red, yellow, and green.
Business students count a large bag of Skittles and find 265 red,
279 purple, 303 yellow, 271 green, and 212 orange candies.
a. Set up the competing hypotheses to test if at least one
proportion is different than the value claimed by MARS.
b. Calculate the value of the test statistic and determine the
degrees of freedom.
c. Compute...

According to M&Ms Web site, each package of the milk
chocolate candies typically contain 14% brown, 13% red, 14% yellow,
16% green, 24% blue, and 20% orange M&Ms. You go to the store
and buy a standard-sized package. When you open it, you find that
it contains 51 M&Ms, distributed as follows: Color Brown Red
Yellow Green Blue Orange Frequency 8 4 10 4 11 11 Over the long
run, what is the probability that the first M&M you select...

In a bag of M & M's, there are 80 M & Ms, with 11 red
ones, 12 orange ones, 20 blue ones, 10 green ones, 18 yellow ones,
and 9 brown ones. They are mixed up so that each candy piece is
equally likely to be selected if we pick one.

Plain M&M's come in 6 different colors (Blue, Orange, Green,
Yellow, Red, Brown) and are produced at two different plants.
M&M's that come from a plant in Tennessee are supposed to have
the following distribution of colors: 20.7% Blue; 20.5% Orange;
19.8% Green; 13.5% Yellow; 13.1% Red and 12.4% Brown. Quality
control at the plant is concerned the machine is not working
correctly and that it is producing a different distribution of
colors. They take a random sample of 940...

A package of 100 candies are distributed with the following
color percentages: 12% red, 22% orange, 14% yellow, 12%
brown, 24% blue, and 16% green. Use the given sample data to test
the claim that the color distribution is as claimed. Use a 0.025
significance level.

Use the distribution below to test that Plain M&Ms follow
the stated distribution. Discuss your choice of ?. Would a
different ? have changed your conclusion?
M&M states the following distribution for Plain M&Ms:
Red = 13%, Orange = 20%, Yellow = 13%, Green = 20%, Blue = 20%,
Brown = 14%
Total amount of Plain M&Ms: 678
Red=69 Orange=216 Yellow=75 Green=61 Blue=187 Brown=70

M&M chocolates come in six different colors: red, orange,
yellow, green, blue and brown. A market researcher believes that
the six color proportions are not evenly distributed for the
population of all M&Ms produced. To test this theory, he first
selects his significance level to be 10% and then sets up the
following goodness of fit test null hypothesis: H0: All 6 M&M
color proportions are equal to 1/6 Suppose that the six colors are
evenly distributed for the population...
