I The comparison of two populations is the simplest kind of comparative studies (Chapter 1). I The mean and variance of population i , i = 1 , 2, are denoted by i , 2 i .

I The comparison of two populations is the simplest kind of comparative studies (Chapter 1). I The mean and variance of population i , i = 1 , 2, are denoted by i , 2 i . If the two populations are Bernoulli, then i = p i , and 2 i = p i (1 p i ).

I The comparison of two populations is the simplest kind of comparative studies (Chapter 1). I The mean and variance of population i , i = 1 , 2, are denoted by i , 2 i . If the two populations are Bernoulli, then i = p i , and 2 i = p i (1 p i ). I The comparison will be based on a simple r.s. from each of the two populations: X 11 ,..., X 1 n 1 from population 1, and X 21 ,..., X 2 n 2 from population 2.
