Are families with kids (population 1) less likely than families without kids (population 2) to display holidaydecorations? To answer the question, we would like to construct a 95% confidence interval using thefollowing statistics.37 of the 71 families with kids surveyed display holiday decorations and 25 of the 73 families without kidssurveyed display holiday decorations.a. The 95% confidence interval is (please show your answers to 3 decimal places)« Pi - P2b. We observe thatO all values in the confidence interval are above zerothe confidence interval contains zeroO all values in the confidence interval are below zeroc. From the confidence interval above, we can conclude that, in general, families with kids areSelect an answer V likely than families without kids to display holiday decorations with 95%confidence.

You are interested in constructing a 90% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 427 randomly selected caterpillars observed, 45 lived to become butterflies. a. Use 3 decimal places to complete the following statement: With 90% confidence the proportion of all caterpillars that lived to become a butterfly is between and . b. If many groups of 427 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.
