Explanation / Answer

We are given that

x1 = 18 , n1 = 90 and x2 = 23 , n2 = 50 .

Now in order to calculare the sample proportions , we must calculate what percentage of n1 is x1 and what percentage of n2 is x2

so sample proportion p1 = x1/n1 = 18/90 = 0.2

and sample proportion p2 = x2/n2 = 23/50 = 0.46
