Refer to the topic resources to review the documentation, questionnaires, and general information pertaining to the YRBSS and YRBS. Then use the 2015 "Youth Risk Behavior Surveillance System Dataset" and conduct a two-sample t-test to determine if weight (in kg) differs by sex. Submit the SPSS output for the t-test.

- What are the null and alternative hypotheses?
- What is the decision rule?
- What is the test statistic and p-value?
- Interpretation of the t-test results (What was done? What was found? What does it mean? What suggestions are there for the creation of a health promotion intervention?).
