For questions 17-20, create a T Score with a mean of 50 and a standard deviation of 10 on the raw scores (Score) that ten students achieved on a measure of intelligence: Student 1: 116 Student 6: 108 Student 2: 103 Student 7: 105 Student 3: 112 Student 8: 88 Student 4: 98 Student 9: 109 Student 5: 114 Student 10: 104 What statement is true of the skewness of the distributions of Score, Z Score, and T Score? Skewness is the same for Score and T Score but different for Z Score Skewness is the same for Score and Z Score but different for T Score Skewness is the same for Z Score and T Score but different for Score Skewness is the same for all three
