Question

wants to revious the par Problem 2. A political science student at CMU wants to estimate the percent of students who are registered to vote for the next election. Data from previous years showed that the average percent is 0.75 with variance of 0.15. Please propose a prior for the parameter of interest using the information provided. Hint: y Normal, 8), mean(y) = x and variance (y) = 8, y Gammala,B), mean(y)=a8 and variance (y) = 08, yw betala,), mean(y)=m=ofs and variance (y) = +8+1

Answer 1

here the parameter of interest is the percentage (prop ortion) of students who are registered to vote for the next election.since the proportion is lies between 0 to one so we choose such prior which variable range is (0, 1). therefore we will be choose beta distribution. therefore y~ beta (a, b)
