Question

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 90 freshmen is selected. Round the answers to at least four decimal places as needed. Part: 0/6 Part 1 of 6 (a) Is it appropriate to use the normal approximation to find the probability that less than 29% of the freshmen in the sample are planning to major in a STEM discipline? It is $\text{appropriate}$ to use the normal curve, since $np = 0.488 < 10$ and $n(1 - p) = 0.7290 \ge 10$.

It is appropriate to use the normal curve, since np = 0.488 < 10 and n(1 - p) = 0.7290 ≥ 10.
