Problem 1:
Mrs. Marasigan is a veterinarian. One morning, she asked her secretary to
record the service time for 15 customers in minutes. Given the value of 2nd decile
and 3rd quartile, interpret each value.
17, 20, 25, 28,28, 32, 35, 37, 46, 47, 52, 55, 55, 56,60
1. D2 = 3.2 D2 is the third element, Therefore, D2 = 25.
It means that 20% of the customers' service time is less than or equal to 25 minutes
and the remaining 80% customers' time is higher than 25 minutes.
2. Q3 = 12 Qais the 12th element. Therefore, Q3 = 55. It means that 75% of the
customers' service time is
