Anova De Un Factor

M&M: Con un nivel de significancia de 0.05, pruebe o desmienta la suposición de que el peso medio de los dulces M&M es el mismo para cada una de las seis poblaciones de diferente color. Si la intención de Mars, Inc., es fabricar los dulces de modo que las poblaciones de diferente color tengan el mismo peso medio, ¿sugieren los resultados que la compañía enfrenta un problema que amerita corregirse?
