Explanation / Answer
Solution:-
a) The proportion of the children are obese is 0.352
Number of obese students = 250
Total number of students = 710
The proportion of the children are obese = 250/710 = 0.352
b) Proportion of the elementary school children are overweight or obese is 0.7746.
Number of obese students or overweight studnets = 250 + 300 = 550
Total number of students = 710
Proportion of the elementary school children are overweight or obese = 550/710 = 0.7746
c) The proportion of the normal weight children are in high school is 0.2254
Number of normal weight children = 160
Total number of students = 710
The proportion of the normal weight children are in high school = 160/710 = 0.2254
d)
1) We were surprised about the overweight and obese totals because the total proportion of the elementary school children are overweight or obese is 0.7746 which is quite high.
