Future scientists: Education professionals refer to science, technology, engineering, and mathematics as the STEM disciplines. A research group reported that 29% of freshmen entering college in a recent year planned to major in a STEM discipline. A random sample of 90 freshmen is selected. Use Excel as needed. A new sample of 140 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. Round the answer to at least four decimal places.
