The sample mean is
The sample median is
c. By consulting the most recent census data, we found that the mean age and
median age of all residents are 36.5 years and 35.9 years, respectively. Decide
whether those descriptive measures are parameters or statistics, and use statistical
notation to express the results.
The mean and median age of all residents are
The population mean is
11
The population median is
= 36.5.
= 35.9.
