A psychologist has prepared an "Optimism Test" that is administered yearly to graduating college seniors to analyze any changes in optimism. The test measures how each graduating class feels about its future – the higher the score, the more optimistic the class. Last year's class had a mean score of µ=17.00. A sample of 10 seniors from this year's class was selected and tested. The scores for these seniors were as follows: 20 19 20 14 18 19 22 24 23 16 For your convenience: EX = 195 and E X2 = 3887
