Explanation Given: The given table shows the ages of the firefighters in the Cleansburg fire department. Age 25 27 28 29 30 Frequency 2 7 6 9 15 Age 31 32 33 37 39 Frequency 12 9 9 6 4 Approach: The five number summary of the data set is given by, 1. The smallest value of the ordered data set. 2. The first quartile Q 1 of the ordered data set. 3. The median M of the ordered data set. 4. The third quartile Q 3 of the ordered data set. 5. The largest value of the ordered data set. The first quartile, the median and the third quartile is the 25 th percentile, 50 th percentile and the 75 th percentile of the ordered data set respectively. Formula used: The p th percentile of N data points is given by, p th percentile = ( p 100 ⋅ N ) t h value. Calculation: The given data set is, Age 25 27 28 29 30 Frequency 2 7 6 9 15 Age 31 32 33 37 39 Frequency 12 9 9 6 4 From the ordered data set, it is observed that the smallest value is 25 and the largest value 39. Thus, Minimum = 25 and Maximum = 39 . The sum of all the frequencies is given by, N = 2 + 7 + 6 + 9 + 15 + 12 + 9 + 9 + 6 + 4 = 79 The first quartile Q 1 of N data points is given by, Q 1 = ( 0.25 × N ) t h value. Substitute 79 for N in the above formula. Q 1 = ( 0.25 × 79 ) t h = 19.75 Since, 19.75 is not a whole number, the first quartile is the 20 th value of the data set. 2 + 7 = 9 2 + 7 + 6 = 15 2 + 7 + 6 + 9 = 24 The value 24 corresponds to the age 29 of the firefighters To determine b) To plot: The box plot of the given data set.
