    (a) What are the observational units and variable units of interest in this study? Also specify the population or process of interest.

    (b) State and null and an alternative hypothesis about the value of pi (in words and symbols)

    (c) We can assess the strength of evidence against the null hypothesis by treating 897 current athletes as a random sample from the process of athlete determination at Brown. If we initially give the university the benefit of the doubt and assume the nully hypothesis is true, does the Central Limit Theorem for a sample proportion apply here? Explain.
