Which of the following represents H₁ in a chi-squared goodness-of-fit test to see if all 5 colors of a certain candy appear in the same proportion in the population? A)H₁: p₁ = p₂ = p₃ = p₄ = p₅ = 0.20. B)H₁: At least one proportion is not equal to 0.20. C)H₁: None of these proportions are equal. D)None of these choices.

The given string represents the counts of each color in the sample. Since we are testing if all 5 colors appear in the same proportion (i.e., with equal probability), the null hypothesis is that each proportion is 0.20. Therefore, the alternative hypothesis is that at least one proportion is not equal to 0.20. Hence, the correct answer is (B) "H₁: At least one proportion is not equal to 0.20."
