Question1: A 1976 study of smokers under thirty years of age who delivered premature babies reported an infant survival rate of 84%. Assume the researchers would like to estimate the current survival rate. Based on the assumption that survival rate today would be roughly similar to the survival rate in 1976, compute the required sample size required to find the true proportion to within 0.05 with 90 percent confidence.
