Probability
Of 20 smokers 9 had heart attacks. Suppose that prior to the experiment we believe that the true proportion 0 of heart attacks in this population of smokers folows a beta distribution with parameters a = 1 and B = 1. Give your best estimate of the probability of the logical proposition that [0 < 0.2]. HINT: Use t° (1 – t)*dt z xª+1/(a(a + 1)) ok for the numbers in this problem. O 97
