Answer:

The proportion of people in your sample whose response is yes=40 people

Explanation:

Step 1: Determine the statistical proportion that will say yes

Proportion=40%=40/100=0.4

Step 2: Determine the proportion in the sample that will say yes

The proportion in the sample can be expressed as;

P=S×Z

where;

P=proportion in the sample

S=statistical proportion

Z=sample size

In our case;

P=unknown to be determined

S=40%=40/100=0.4

Z=100

replacing;

Proportion in the sample=0.4×100=40

The proportion of people in your sample whose response is yes=40 people
