Answer 1

A. No , it would be wrong to depict the data in a single pie chart since the data represents smokers within four different groups.

The data shows the percentage of smokers in each age group of a sex. However in the pie chart we would like to show out of all smokers in the age group of 18 to 29 of both sexes, what percentage belongs to each of the four groups. This data is not available.

B. The correct statement is that the corrected median will not change , because the erroneous and corrected values are both larger than the original median.
