Use the following to answer the questions below:

Suppose we are interested in comparing the proportion of male students who smoke to the proportion of female students who smoke. We have a random sample of 150 students (60 males and 90 females) that includes two variables: Smoke = "yes" or "no" and Gender = "female (F)" or "male (M)." The two-way table below summarizes the results.

 ​ Smoke = Yes Smoke = No Sample Size Gender = M 9 51 60 Gender = F 9 81 90

The standard error is estimated to be 0.056. Find (in the context of this data situation) a 95% confidence interval for the difference in the proportion of smokers between male and female students, Round the margin of error to three decimal places.

▸ -0.062 to 0.162

▸ -0.006 to 0.106

▸ 0.475 to 0.525

▸ -0.118 to 0.218
