Multiple Choice

A tennis player makes a successful first serve 70% of the time.If she serves 80 times,is it appropriate to use a normal model to approximate the distribution of the number of good first serves? Assume that each serve is independent of the others.

A) No;normal model cannot be used to approximate the distribution because nq < 10
B) Yes;normal model with μ = 56 and σ = 16.80 can be used to approximate the distribution
C) Yes;normal model with μ = 56 and σ = 4.10 can be used to approximate the distribution
D) Yes;normal model with μ = 24 and σ = 16.80 can be used to approximate the distribution
E) No;normal model cannot be used to approximate the distribution because np < 10
