he drug Ritalin is designed to stimulate the central nervous system. In a random sample of 252 boys aged ten-twelve years old, it was found that 44 of the boys were taking Ritalin. It is known that the proportion of all boys aged 13 – 15 who take Ritalin is 24%. A researcher claims that the population proportions of boys who take Ritalin aged 10 – 12 are different than boys aged 13 – 15. Can you support this claim at the 5% significance level? d. Write a complete sentence describing what a Type II error is in context. e. Suppose that we used a 1% significance level. What would your decision and conclusion be?
