A large school district notices that about 26% of its sophomore
students fail Algebra I. An online education supplier suggests the
district try its new technology software, which is designed to
improve Algebra 1 skills and, thus, decrease the number of students
who fail the course. The new technology software is quite
expensive, so the company offers a free, one-year trial period to
determine whether the Algebra 1 pass rate improves. If it works,
the district will pay for continued use of the software. What would
happen if the school district makes a Type I error?
