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 95 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? appropriate to use the normal curve, since np = 24.7 > It is andn (1 - p) Part 2 of 6 Part 3 of 6 Part 4 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 0.6700 = 70.3 > A new sample of 120 freshmen is selected. Find the probability that less than 28% of the freshmen in this new 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 0.6915 Part 5 of 6 10. ▼ 10 Find the probability that the proportion of freshmen in the sample of 120 who plan to major in a STEM discipline is between 0.32 and 0.38. Part: 5 / 6 The probability that the proportion of individuals in the sample of 120 who plan to major in a STEM discipline is between 0.32 and 0.38 is 0.0656 Part 6 of 6 Find the probability that more than 31% of the freshmen in the sample of 120 are planning to major in a STEM discipline. The probability that more than 31% of the freshmen in the sample of 120 are planning to major in a STEM discipline is 0.1059 Would it be unusual if less than 28% of the freshmen in the sample of 120 were planning to major in a STEM discipline? It (Choose one) be unusual if less than 28% of the freshmen in the sample of 120 were planning to major in a STEM discipline, since the probability is
