A medical researcher collected the systolic blood pressure reading for a random sample of n = 30
Question:
A medical researcher collected the systolic blood pressure reading for a random sample of n = 30 female students under the age of 21 who visited the Student's Health Service. The blood pressures are:

(a) Use a normal (120, 152) prior for . Calculate the posterior distribu tion of p. (b) Find a 95% Bayesian credible interval for u. (c) Suppose we had not actually known the standard deviation . In stead, the value = 12 was calculated from the sample and used == in place of the unknown true value. Recalculate the 95% Bayesian credible interval.
