Required informationSleep apnea is a disorder in which there are pauses in breathing during sleep. People with this condition must wake upfrequently to breathe. An article reported that in a sample of 427 people 65 and over, 106 of them had sleep apnea.Find the sample size needed for a 99% confidence interval to specify the proportion to within ±0.03. (Round up the final answer to thenearest integer.)The sample size needed is.............

The formula for the sample size is as follows: Here, zα/2 is the critical value at 99% confidence…

You are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 424 randomly selected caterpillars observed, 50 lived to become butterflies. a. With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between and . b. If many groups of 424 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.
