Inferential Statistics

(d) Carry out a test of significance to decide whether Cal Poly students tend to carry less than 10% of their body weight.

1. Define the parameter(s) of interest. [Hint: Is the response variable quantitative or categorical?]

2. State the hypotheses both in symbols and in words.

3. Identify an appropriate test procedure and state and if a theory-based test comment on the validity conditions.

4. Determine a test statistic and p-value for these hypotheses. [Hint: Which applet? Review the Labs page if necessary.] Also report a 95% confidence for the parameter of interest.

Copy the relevant output into your report.

5. State your decision and summarize your conclusions in context. Be sure to reference information from the output! (Meaning, cite the test statistic, p-value, and confidence interval!)
