The two-way table below summarizes the results.

-Percentiles of the bootstrap distribution (based on 5,000 samples) are provided. Use the percentiles to provide a 98% confidence interval for the difference in the proportion of smokers between male and female students.

A) -0.078 to 0.189
B) -0.056 to 0.164
C) -0.039 to 0.144
