Mars Company claims that the colors in a standard bag of M&Ms® candy are of equal proportion. To test this claim, researchers took a random sample of 210 M&Ms® and counted the number of each color. The results are shown in the table.
Color | Count
----------------
Red | 34
Orange | 33
Yellow | 31
Green | 35
Blue | 33
Brown | 44
What is an appropriate null hypothesis to test whether the colors of M&Ms® are of equal proportion?
A. H0: μ = 35, where μ is the mean number of each color
B. H0: p = π, where π is the proportion of each color
C. H0: n1 = n2 = n3 = n4 = n5 = n6 = 35, where ni is the number of each color
D. H0: p₁ = p₂ = p₃ = p₄ = p₅ = p₆ = π, where pᵢ is the proportion of each color
E. H0: p₁ = p₂ = p₃ = p₄ = p₅ = p₆ = π, where pᵢ is the true proportion of each color
