1 out of every 5 means \(\frac{1}{5}=0.2\). This means \(0.2*100=20\) percent.

Margin of error, according to the statistician, is 1.5%.

So 20% can be 1.5% less or 1.5% more.

We want the MAXIMUM PERCENTAGE, so we take \(20+1.5=21.5\) percent. That is the maxium percentage of individuals who can own a bike.
