A scientific study was conducted to determine the hours of sleep that college students get per night. The study surveyed 32 college students and obtained the following data: 7.9, 7.9, 8.8, 8.2, 8.9, 8.3, 8.6, 7.9, 8.6, 8, 8.7, 8.4, 8.8, 8.1, 8.7, 8.9, 7.8, 8.8, 8.4, 7.7, 8.3, 8.3, 8.6, 9, 8.1, 8.5, 8.8, 8, 8.4, 8.5, 7.6, 8 Assuming the population standard deviation is σ=0.43σ=0.43, 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.
