Directions: Perfrom an appropriate significance test to determine whether or not the average number of polys in the treatment group is less than the average number of polyps in the placebo group. 1.Choose the correct null and alternative hypothesis. Note: μ1μ1 represents the average number of polyps for the placebo group and μ2μ2 represents the average number of polyps in the treatment group. 2.Compute the test statistic. Round your answer to 4 decimal places. 3.Compute the p-value. Round your answer to 4 decimal places.

- **Placebo Column:** Contains values ranging from 6 to 63, with most entries clustering around the central values.
- **Treatment Column:** Includes values ranging from 1 to 34, showing a wide variation. Note that the last two entries are missing values.
This data can be used to analyze the effects of the treatment compared to the placebo and identify any significant differences or patterns in the results.
