A scientific study was conducted to determine the hours of sleep that college students get per night. The study surveyed 20 college students and obtained the following data: 8, 8.3, 7.8, 7.7, 8.6, 8.1, 7.7, 8.5, 8.1, 8.2, 8.2, 7.9, 8.5, 7.9, 8.3, 8.2, 7.8, 7.8, 7.8, 7.7 Assuming the population standard deviation is σ=0.31σ=0.31, construct a 86% confidence interval for the average hours of sleep per night that college students get. xˉ=x̄= α2=α2= zα2=zα2= Margin of Error: E=E= We are 86% confident that college students get an average of between hours and hours of sleep per night.
