PROBLEM 1. Suppose in a certain municipality, it is of interest to study the peoples' attitudes towards the proposal to ban anti-government magazines. The municipality was divided into four strata. The table below shows the number of persons in each stratum. Suppose a total sample size of n = 160 is to be allocated among the four strata. (a) How will this sample size be allocated among the four strata using equal allocation? n1 = n2 = n3=_____, and n4 in this order. No need to show computation. n n Stratum ID N₁ Equal allocation Proportional allocation
