M&M's cаndies аre prоduced in the fоllоwing proportions: 20% аre yellow, 20% are red, 10% are orange, 10% are blue, 10% are green, and 30% are brown. On her way home from work one day, Kamala bought a bag of M&M's. She got 29 yellow candies, 23 red, 12 orange, 14 blue, 8 green, and 20 brown. If Kamala were to statistically test whether the proportions of colors in her bag were unusual, what would be the appropriate degrees of freedom (df)?
