(Hypothetical) In a major national survey of crime victimization, the researchers found that 17.2% of Americans age 12 or older had been a victim of crime. The size of the sample was 144,400. Estimate the percentage of US adults who were victims at the 95% confidence level. State in words the meaning of that result. Estimate the percentage of victims at the 99% confidence level. Imagine that the Sample size was cut in half but the survey found the same value of 17.2% for the percentage of victims. By how much would the 95% confidence level increase? By how much would the 99% confidence interval increase?
