    a. 17th percentile First, take the data and sort it in increasing order, getting: 98 101 117 121 122 127 130 137 138 143 145 152. The score of 117 is greater than 2 of the scores out of a total of 12 scores. So the percentile rank is 2/12 = 0.1666667 = 16.66667, or the 17th percentile. Therefore the answer is "a. 17th percentile"
