Step-by-Step explanation 1. The values in this data set in ascending order are: 20, 22, 23, 23, 23, 23, 24, 25, 26, 26, 27, 27, 27, 28, 28, 29, 29, 31, 31, 31, 32, 33, 33, 33, 34, 35, 35, 36, 37, 43 Number of laptops built everyday for sample (n)= 30 Number of values in the data set below 32 = 21 Total number of values = 30 Percentile rank = p / 100 x (n + 1) Where : p = percentile n = Number of items Hence, we first need to calculate the percentile before computing the percentile rank Percentile = (number of values below the sample) + (total number of values in the data set) x 100 = (21) + (30) x 100 = 70 Percentile rank = p / [100 x (n + 1)] = 70 / [100 x (30 +1 )] = 0.02 = 2 nd percentile rank
