A section of an Introduction to Psychology class took an exam under a set of unusual circumstances. The class took the exam in the usual classroom, but heavy construction noise was present throughout the exam. For all previous exams using the same format and same questions, student scores were normally distributed with a mean of µ = 75.00 and a population standard deviation (sigma) = 10.50. To understand the possible effects of the construction noise, you have been asked to...
