What is the % CV for a set of data with a standard deviation of 0.22 and mean of 1.75?

When a test has high diagnostic sensitivity,  it is a good screening test because there are very few false negative results and thus, will indicate, through a positive result, that the person has the disease or more testing is necessary to rule disease out.
