Question

HELP PLEASEEE!

In a survey, editors of a magazine asked 200 people whether or not they smoke and whether or not they exercise regularly (more than twice a week). The results are summarized in the table below.

Answer 1

(a) 75%

(b) 82%

Explanation:

In a table like this take row and column totals first. That will help you answer almost any question that is asked regarding the statistics and percentages

Column Totals

Column total for number of people who smoke = 6 + 44 = 50

Column total for number of people who do not smoke = 30 + 120 = 150

Row Totals

Row total for number of people who exercise regularly = 6 + 30 = 36

Row total for number of people who do not exercise regularly = 44 + 120 = 164

Total number of people surveyed = 200

Percentage of adults who do not smoke = 150/200 = 75%

Percentage of adults who do not exercise regularly = 164/200 = 82%
