Solution

Set up null and alternate hypotheses as

H0: All colours are equally preferred

Ha:Atleast two colours are equally likely

Two tailed chi square test

Prepare contingency table

df = 5

p value = 0.3102

As p > 0.05 accept null hypothesis

There is no statistical evidence to prove that  a greater proportion of blue M&Ms is in a milk chocolate bag than in a peanut bag
