Part 1 of 6
Your Answer is correct Is it appropriate to use the normal approximation to find the probability that less than32%of the freshmen in the sample are planning to major in a STEM discipline? Itisappropriate to use the normal curve, since=np 19.510 and=n1p 55.510.
Find the probability that less than32%of the freshmen in the sample are planning to major in a STEM discipline. The probability that less than32%
of the freshmen in the sample are planning to major in a STEM discipline is0.8819.
A new sample of120
freshmen is selected. Find the probability that less than29%of the freshmen in this new sample are planning to major in a STEM discipline. The probability that less than29
%of the freshmen in the sample are planning to major in a STEM discipline is0.7731
