Suppose a survey of 36 people determined that the sample mean time spent on the internet was 8.2 hours with a sample standard deviation of 9.8 hours. What is the UPPER LIMIT of a 90% confidence interval? Note: Enter X.XX AT LEAST ONE DIGIT BEFORE THE DECIMAL, TWO AFTER and round up. Thus, 7 is entered as 7.00, 3.5 is entered as 3.50, 0.2750 is entered as 0.28, -0.564 is entered as -0.57
