Which substance has the highest percentage of lifetime users?4. Expressed as a percentage, what was the difference between marijuana and nicotineas the greatest drug problem? -In statistics, the percentage is the same or equivalent to the proportion (p).Percent means per 100. For example, if there are 1,000 residents in a town, and 60% areDemocrats, then, on average, 60 out of each 100 are Democrats. You determine thetotal number of Democrats by converting the percentage to a proportion, .60, andmultiplying .60 x 1,000, which equals 600.-To determine a percentage, we divide the part by the whole and multiply by 100. So, if8 out of 234 seniors are reported to have tried Meth, we calculate the percentage:8/234 0.0342 and multiply 0.0342 x 100= 3.42%.-Remember: when you multiply by 10, move the decimal point one place to the right3;when you multiply by 100, move the decimal point two places to the right, etc.Answer the questions that follow the Table belowAdolescents at three drug treatment centers were surveyed.
