-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.

Aspirin III: Decision and Conclusion Regarding the experiment in the data frame Aspirin from the abd package, the researchers wanted to know whether or not taking aspirin affects one's risk of developing cancer. Recall that they defined their parameters as follows: p1 = the proportion of ALL individuals who would develop cancer, if all of them were to take aspirin like the subjects in the Aspirin group did. p2 = the proportion of ALL individuals who would develop cancer, if all of them were to take a placebo, like the subjects in the placebo group did. They ran the code for a two-sided significance test and got the following results: ## ## ## Inferential Procedures for the Difference of Two Proportions p1-p2:## cancer grouped by treatment ## ## ## Descriptive Results:## ## yes n estimated.prop## Aspirin 1438 19934 0.07214## Placebo 1427 19942 0.07156## ## ## Inferential Results:## ## Estimate of p1-p2: 0.0005805 ## SE(p1.hat - p2.hat): 0.002586 ## ##…
