Please hurry! The back-to-back stem and leaf plot below shows the ages of patients seen by two doctors in a family clinic in one day. Compare the ages of the patients of Doctor 1 and Doctor 2 using the mean and the median of each data set.

Doctor 1 :

Mean = 12

Median = 12

Doctor 2 :

Mean = 16

Median = 18.5

Step-by-step explanation:

Data from the stem and leaf plot :

Doctor 1:

Age of the patients ( from the center to the left side )

1, 1, 2, 3, 7, 9, 15, 17, 18, 20, 22, 29

Mean age of patients :

Sum. Of ages / number of patients

= 144 / 12

=12

Median = 0.5(n+1)th term

n = 12

Median = 0.5(12 + 1)th term = 6.5th term

= (6th + 7th term)/2

= (9 + 15)/2

= 24/2 = 12

Doctor 2 :

patients mean age : (from the center to the right)

2, 2, 3, 9, 13, 17, 20, 20, 22, 23, 26, 35

n = 12

Mean = Sum of ages/ n

= 192/12

= 16

Median = 0.5(12 + 1)th term = 6.5th term

Median = (6th + 7th term)/2

= (17+20)/2

= 37/2 = 18.5

Doctor 1 : Mean = 12     /     Median = 12

Doctor 2 : Mean = 16     /     Median = 18.5

Data from the stem and leaf plot :

Doctor 1:   Age of the patients:   1, 1, 2, 3, 7, 9, 15, 17, 18, 20, 22, 29

Doctor 2 :  Age of the patients:   2, 2, 3, 9, 13, 17, 20, 20, 22, 23, 26, 35

Both doctor 1 and 2 had 12 patients that day.

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
