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 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 \( np = 22.1 \geq 10 \) and \( n(1-p) = 62.9 \geq 10 \).
