Part 3 of 6 A new sample of 140 freshmen is selected. Find the probability that less than 29% of the freshmen in this new sample are planning to major in a STEM discipline. The probability that less than 29% of the freshmen in the sample are planning to major in a STEM discipline is 0.7910 Part: 3 / 6 Part 4 of 6 Find the probability that the proportion of freshmen in the sample of 140 who plan to major in a STEM discipline is between 0.32 and 0.36. The probability that the proportion of individuals in the sample of 140 who plan to major in a STEM discipline is between 0.32 and 0.36 is

Future scientists: Education professionals refer to science, technology, engineering, and mathematics as the STEM disciplines. A research group reported that 26% of freshmen entering college in a recent year planned to major in a STEM discipline. A random sample of 85 freshmen is selected. Round the answer to at least four decimal places. Part 1 of 6 Is it appropriate to use the normal approximation to find the probability that less than 28% of the freshmen in the sample are planning to major in a STEM discipline? It is appropriate to use the normal curve, since np = 22.1 2 ▼ 10 andn (1 – p) = | 62.9 > 10. Part 2 of 6 Find the probability that less than 28% of the freshmen in the sample are planning to major in a STEM discipline. The probability that less than 28% of the freshmen in the sample are planning to major in a STEM discipline is 0.6628
