Question
Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use the binomial distribution to find the indicated probabilities. A survey of adults found that 8% say their favorite sport is auto racing You randomly select 300 adults and ask them to name their favorite sport. Complete parts (a) through (d). Determine whether a normal distribution can be used to approximate the binomial distribution. Choose the correct answer below. No, because nqExplanation / Answer
p = 0.08 , n = 300
np = 300 *0.08 = 24
nq = 300 *0.92 = 276
option C ) is correct np > 5 , nq> 5
P(X< 29)
P(p^< 29/300)
P(p^< 0.09666666666)
P(Z < ( 0.09666666666 - 0.08)/sqrt(0.08*0.92/300)
=P(Z < 1.06407066302)
=0.8564
correct graph option A)
