Suppose that the proportion of all American adults that fit the medical definition of being obese is 0.23. A large medical clinic would like to determine if the proportion of their patients that are obese is higher than that of all American adults. The clinic takes a simple random sample of 30 of their patients and finds that 9 patients in the sample are obese.
-Describe the parameter of interest in the context of this problem. What is the appropriate statistical symbol for this parameter?
A) $\pi$= proportion of the random sample of 30 patients that are obese
B) $\pi$=proportion of all patients at the large medical clinic that are obese
C)$ \hat{p} $= proportion of the random sample of 30 patients that are obese
D$ \hat{p} $= proportion of all patients at the large medical clinic that are obese
