Step-by-step explanation:

Calculation for what The sensitivity of the physical examination was

Using this formula

Sensitivity=Positive physical examination cases/Physical examination screening for breast cancer

Let plug in the formula

Sensitivity=5,500 cases / 7600 women

Sensitivity=0.7237*100

Sensitivity=72.37%

Therefore The sensitivity of the physical examination was 72.37%
