Goals:

-I can construct and interpret a confidence interval for a population proportion -I can determine critical values for calculating a confidence interval

1) Recent studies have shown that not everyone can roll their tongue. Researchers in the study observed an SRS of 300 adults and found 68 of those involved in the study could roll their tongue. Construct and interpret a 90% confidence interval for the true proportion of adults who can roll their tongue. Be sure to follow the State, Plan, Do, Conclude model described in the powerpoint/textbook.
