When a dermatologist suspects that skin may show signs of disease or cancer they will likely take a skin biopsy for analysis. This process involves removing a small portion of the affected skin. In a 2017 study, the proportion of skin biopsies that came back as benign skin was p=0.051=0.051.

If the study included 340340 biopsies, are the conditions met to use a normal distribution approximation?

np== and n(1p)=(1-)=

• The conditions are met
• The conditions are not met
