Question
Conduct the hypothesis test and provide the test statistic and the critical value, and state the conclusion.
A company claims that its packages of 100 candies are distributed with the following color percentages:12% red, 21% orange, 16% yellow, 11% brown,
23% blue, and 17% green. Use the given sample data to test the claim that the color distribution is as claimed. Use a 0.01 significance level.

The test statistic is
(Round to two decimal places as needed.)
The critical value is
(Round to two decimal places as needed.)
State the conclusion
________H0. There______sufficient evidence to warrant rejection of the claim that the color distribution is as claimed.
Expert Solution
Step 1
The null and alternative hypothesis are stated as,
Null hypothesis:
The distributions are the same.
Alternative hypothesis:
The distributions are different.
The expected values are,
Color | Number in package | Percent | Expected frequency |
Red | 13 | 12% | |
Orange | 25 | 21% | |
Yellow | 10 | 16% | |
Brown | 6 | 11% | |
Blue | 27 | 23% | |
Green | 19 | 17% |
The test statistic is,
Thus, the test statistic is 6.29.
