The dotplot shows the cholesterol level of 93 adults from the 2010 NHANES data.

a. A total cholesterol level of 240mg/dL (milligrams per deciliter) or more is considered unhealthy. Report the number of people in this group with unhealthy cholesterol levels.
b. Knowing there are a total of 93 people in this sample, report the percentage of people with unhealthy total cholesterol levels. How does this compare with an estimate from 2010 that 18% of people in the United States had unhealthy cholesterol levels?
