Suppose a computer chip manufacturer rejects 4% of the chips produced because they fail presale testing.If 135 chips are picked at random,is it appropriate to use a normal model to approximate the distribution of the number of bad chips?
A)No;normal model cannot be used to approximate the distribution because np < 10
B)Yes;normal model with μ = 129.6 and σ = 2.28 can be used to approximate the distribution
C)Yes;normal model with μ = 5.4 and σ = 2.28 can be used to approximate the distribution
D)No;normal model cannot be used to approximate the distribution because nq < 10
E)Yes;normal model with μ = 5.4 and σ = 5.18 can be used to approximate the distribution
