A psychologist wants to estimate the amount of math anxiety that the population of high school students experience prior to taking their first algebra course. On the first day of class he asks a sample of 36 students to answer the question, “How anxious do you feel when you know you have to do math problems?” They each responded using a 100-point scale with 1 = not at all anxious and 100 = extremely anxious. The mean reported anxiety score for this sample was 58 with a standard deviation of 30 Compute the upper and lower boundaries for this 95% confidence interval.     LB = 66.45, UB - 49.55     LB = 28, UB = 88     LB = -5.00, UB = 5.00     LB = 47.86, UB = 68.15     LB = -10.15, UB = 10.15
