Answer:
For Doctor 1 --- Mean = 12 Median = 12
For Doctor 2 ---- Mean = 16 Median = 18.5
Step-by-step explanation:
From the leaf and stem plot given in the question we will write down the ages of each patient of Doctor 1 and Doctor 2 individually.
For Doctor 1
Age of the patients ( from the center to the left side )
01, 01, 02, 03, 07, 09, 15, 17, 18, 20, 22, 29
Therefore mean of the patient's age = Total age / number of patients = 144/12 =12
Median = (Sum of 6th and 7th term)/2 = (9 + 15)/2 = 24/2 = 12
For Doctor 2
Age of the patients (from the center to the right)
02, 02, 03, 09, 13, 17, 20, 20, 22, 23, 26, 35
Mean = Total of ages/ 12 = 192/12 = 16
Median = (sum of 6th and 7th term)/2 = (17+20)/2 = 37/2 = 18.5
