A box model is used to calculate a confidence interval in the following scenario:A institution selects 300 households in a town asking about their annual income.They want to construct a confidence interval for the percentage of people havingincome more than $100,000 annually.For each of the following quantities in the box model, select the answer if thequantity is random, not fixed. Leave the quantities that are fixed unselected.O the EV and SE of the sample percentage of households having income more than $100.000 annuallyO the population percentage of households having income more than $100,000 annuallyO the sample percentage of households having income more than $100,000 annuallyO the proportion of 1's in the box model

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.
