QUESTION 21 A random sample of 36 observations was used to estimate the mean SAT scores of applicants at a business college. The 97% confidence interval was found to be (1695, 1825). If we are to increase the sample size to 40 (other factors remain unchanged), the 97% confidence interval for the mean SAT scores would become wider. be the same.

Question 16 A poll asked 1034 American adults if they believe there was a conspiracy in the assassination of President Kennedy, and found that 611 believe there was a conspiracy. Estimate the proportion of Americans who believe in this conspiracy using a 99% confidence interval. Round to three decimal places.

Question 1 く You are interested in constructing a 95% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 450 randomly selected caterpillars observed, 45 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all caterpillars that lived to become a butterfly is between and b. If many groups of 450 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about percent will not contain the true population proportion.
