# Question

Special tables are available for finding confidence intervals for proportions involving small numbers of cases, where the normal distribution approximation cannot be used. For example, given x = 3 successes among n = 8 trials, the 95% confidence interval found in Standard Probability and Statistics Tables and Formulae (CRC Press) is 0.085 < p < 6 0.755. Find the confidence interval that would result if you were to incorrectly use the normal distribution as an approximation to the binomial distribution. Are the results reasonably close?
