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.

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. 

 
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.
