According to the M&M candy company, the expected proportion can be found in Table #11.2.3. In addition, the table contains the number of M&M’s of each color that were found in a case of candy (Madison, 2013). At the 5% level, do the observed frequencies support the claim of M&M? Table #11.2.3: M&M Observed and Proportions
Blue | Brown | Green | Orange | Red | Yellow | Total | |
Observed Frequencies | 481 | 371 | 483 | 544 | 372 | 369 | 2620 |
Expected Proportion | 0.24 | 0.13 | 0.16 | 0.20 | 0.13 | 0.14 |

Questions 45-46: Consider the following partial table of a sample of 60 M&Ms. We count how many of each color are present. We are testing the null hypothesis that each color has the stated proportion. Observed Counts Assumed Proportions Expected Counts 0.24 13 14 0.20 10 0.16 Color Blue Orange Green Yellow Red Brown Total 11 0.14 6 0.13 6 0.13 60 1.00 60 45. If the null hypothesis is correct, how many orange M&Ms do we expect to see...
