Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. Confidence interval = I b. Express the same answer as a tri-linear inequality using decimals (not percents) accurate to three decimal places.

You are interested in constructing a 95% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 426 randomly selected caterpillars observed, 43 lived to become butterflies. a. With 95% confidence the proportion of all caterpillars that lived to become a butterfly is between l land ' i. b. If many groups of 426 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. Aboutl percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about i ' percent will not contain the true population proportion.
