$H_0: The mix are as per percents given\\H_a:Atleast two differ from the above percent.$

(Two tailed chi square test at 5% significance level)

Chi square is calculated as (Obs_exp)^2/Expected

Cashews Brazil nuts Almonds Peanuts Total

Observed 5 6 6 3 20

Expected 40% 15% 20% 25% 1

Expected 8 3 4 5 20

Chi square 1.125 3 1 0.8 5.925

df = 3

p value = 0.1153
