Based on the information given, the probability
of a randomly sampled woman not being
qualified for the internship will be 0.223.
The probability of a randomly sampled woman
not being qualified for the internship will be:
= P(x<20) = P(x=17) + P(x=18) + P(x=19)
= 0.005 + 0.107 + 0.111 = 0.223
Also, the probability that at least 30 percent of
the women in the sample will not meet the age
requirement for the internships will be 0.03216
In conclusion, from the information given,
a woman who does not meet the age
requirement is more likely to be selected with
a stratified random sample than with a simple
random sample.
