In a survey, 200 people were asked if they smoke and whether or not they exercise regularly (more than twice a week). The result

siniylev [52]

Answer/Step-by-step explanation:

a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100

Total no. of people who smoke is given = 4 + 36 = 40

Total people surveyed = 200

% of people who smoke = $\frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent$

a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100

Total no. of people who do not exercise regularly = 36 + 134 = 170

Total people surveyed = 200

% of people who smoke = $\frac{170}{200}*100 = \frac{170}{2}*1 = 85percent$
