Answer:
Based on this sample data, there is enough evidence to suggest that the numbers have changed.
The number of those who do not do regular exercise has reduced from 60% to 54%. The number of those who do sporadic exercise has increased from 25% to 27%. The number of those who engage in regular exercise has increased from 15% to 19%.
So the numbers have changed much.
Step-by-step explanation:
No Regular Sporadic Regular
Exercise Exercise Exercise Total
Estimated proportion 60% 25% 15% 100%
Random sample 255 125 90 470
Random proportion 54% (255/470) 27% (125/470) 19% (90/470) 100%
