The researchers looking into the association between mood and sleep activity among college students are interested in estimating the overall Hours of True Sleep on a Normal night for the students. They collected the data for 76 students. In the following lab, treat this as a sample. Open the lab dataset in Blackboard Learn or from where you previously saved it. Look at the data for HTSNormal What is the sample mean? Calculate this using SPSS. Attach your output. Descriptive Statistics Give the researchers an approximation (or inferred value) for the average HTSNormal and its likely range for the entire student population. Assume the population standard deviation is 0.2. Use a 95% confidence level. What calculation is needed for this approximation, a confidence interval or hypothesis test? A confidence interval will be used Approximate what the average hours of true sleep time will be for the entire student population. Must be done by hand. Round to 3 decimal places and show all your work. Start by calculating the margin of error. Write a statement as to what you would tell the researcher about the accuracy of the average hours of true sleep time for the entire student population.
