2. M&M Statistical Research Project

3. Question 1 Q1: Are the amount of M&M colors in a 21.3 oz bag proportional to the Mars co. claimed proportions? Hypotheses: Ho: Pb = 13% Py = 14% Pr = 13% Pbl = 24% Pg = 16% Po = 20% Ha: not Ho

4. Data M&M Color Observed Colors Brown102 Yellow100 Red59 Blue154 Orange154 Green141 Total710

5. Test Results Decision: Reject Ho Sample Size:710.05 α =.05 Degrees of Freedom:5 Critical Value:11.07 Calc. Critical Value: x² = 22.238 : P-Value: Approx. 0

6. Conclusion Calculated critical value is larger than the test statistic Calculated P-value is smaller than α =.05 Decision: Reject Ho With a 95% confidence level the number of each color of M&Ms are not proportional to the Mars co. claimed values HHHH oooo mmmm eeee pppp aaaa gggg eeee
