An administrator wanted to study the utilization of long-distance telephone service by a department. One variable of interest (let's call it X) is the length, in minutes, of long-distance calls made during one month. There were 38 calls that resulted in a connection. The length of calls, already ordered from smallest to largest, are presented in the following table. 2.5 8.6 co 12.7 15.3 15.5 15.9 15.9 16.1 16.5 17.3 17.5 19.0 19.4 22.5 23.5 24.0 31.7 32.8 43.5 53.3 Which one of the following statements is not true? Select one: O a. The 75th percentile (Q3) is 17.5 minutes O b. There are 2 outliers in X distribution. O C. Q3- Q2 > Q2- Q1 O d. The 25th percentile (Q1) is 4.4 minutes. O e. The 50th percentile is (Q2) 9.4 minutes O f. IQR (Inter-Quartile Range) is 13.1 minutes, O g. X distribution is positively skewed. O h. Range of X is 51.7 minutes. O i. Average x > Median x O j. The percentile rank of 5.9 minutes is 13
