Answer & Step-by-step explanation:
Total people sampled is: 265+159+121= 545
Less than 25 (From 1 to 24.9): 265
At least 25 but less than 30(From 25 to 29.9): 159
Exceeding 30(From 30 to n): 121
Percentages:
Less than 25: 265/545= 0.486*100=48.6%
At least 25 but less than 30: 159/545=0.292*100= 29.2%
Exceeding 30:0.222*100= 22.2%
According to the definition of an obese person (From 30 to n), the 22.2% of the sampled population are obese. Then, yes more than 20% of the are obese.
