The data in Table represent the population of the statistics students and the marks obtained in the examination on hypothesis tests. Knowing that the previous data are from the population with a normal distribution Determine: 1. Using the T distribution. Make a confidence interval for a 95% confidence level. Alpha mean = .05 enter right value XX.XX Table: 0 0 0 0 0 5 10 15 15 15 20 20 25 25 40 45 50 50 55 75 80 85 90 95 105
