# Doctor 2

A doctor noted the Diastolic Blood Pressure (DBP) of a large number of patients. Later, he scrambled the data to keep the privacy of his patients. Based on the scrambled dataset, he finds that the lower inner fence is equal to 50 and the upper inner fence is equal to 100. Find the IQR value, which is defined as the difference between the third quartile and the first quartile.

Little help:

lower inner fence: Q1 - 1.5*IQR

upper inner fence: Q3 + 1.5*IQR

lower outer fence: Q1 - 3*IQR

upper outer fence: Q3 + 3*IQR

in example Q1=a, Q3 = b , IQR = i

lower inner fence: Q1 - 1.5*IQR

upper inner fence: Q3 + 1.5*IQR

lower outer fence: Q1 - 3*IQR

upper outer fence: Q3 + 3*IQR

in example Q1=a, Q3 = b , IQR = i

#### To solve this example are needed these knowledge from mathematics:
