Question
If you were posed with the following, "Are there a greater proportion of blue M&Ms in a milk chocolate bag than in a peanut bag?" of M&M's and " Are the colors evenly distributed in either bag? " Which of the following methods would be appropriate to use to answer questions above? and why?
* Difference between Proportions using Two Independent Samples
* Tests for Independence or Homogeneity
* Goodness of Fit Test
* Two-sample t-test for a difference of means
* Paired t-test for a difference of means
* Ratio of Variance using Two Independent samples
* Sign Test for Two Medians
* Mann-Whitney U Test
Explanation / Answer
For "Are there a greater proportion of blue M&Ms in a milk chocolate bag than in a peanut bag?", Difference between Proportions using Two Independent Samples will be used. Because there are two independent samples one from each bag. and then proportion of blue M&Ms will be compared.
---------------------
For " Are the colors evenly distributed in either bag? " Goodness of fit test (chi sqaure test) should be used. Here we used observed frequncies of each color in bag and compared them with expected frequencies of the colors.
