Question

A quality standard says that no more than 2 percent of the eggs sold in a store may be cracked (not broken, just cracked). In 3 cartons (12 eggs each carton), 2 eggs are cracked.

(a) Calculate a p-value for the observed sample result. Hint: Use Excel to calculate the cumulative binomial probability P(X ≥ 2 | n = 36, ππ = .02) = 1 – P(X ≤ 1 | n = 36, ππ = .02). (Round your answer to 4 decimal places.)

P(X ≥ 2)            

Answer 1

In excel, for p(X<=2)

using the function BINOMDIST

NOW TO GEETHA p(x>2)=1-p(x<=2)

Required probability is p(x>2)=0.0350
