For a sample of 10 patients, serum HDL cholesterol readings
were:

70, 56, 48, 48, 53, 36, 49, 28, 35, 68

Use the Empirical Rule to approximate the percentage of patients
with serum HDL cholesterol within 2 standard deviations of the
mean.
Percent = (whole number)

(d) Use the Empirical Rule to approximate the percent of patients
with serum HDL cholesterol between 35.46 and 62.74.
Percent =  (whole number)

(e) Using the Empirical Rule, we would say almost all of the data
is between
Lower value  (3 decimal places)
and
Upper value  (3 decimal places)
