Question

This two-way table shows the results of a surveyabout gender and time spent exercising.What percent of the people surveyed spent morethan 10 hours exercising each week?A. 17%B. 33%C. 60%D. 61%

Answer 1

WE can see that people who spent more than 10 hours are 1150 + 950=2100. Since the grand total is 3500, the percent is given by

`\frac{\#\text{ people > 10 hours}}{\text{grand total}}*100=(2100)/(3500)*100=60\text{ \%}`

which corresponds to option C.
