Question 333318: After sampling from two binomial populations, we found the following:
p = 0.48 n1 = 100 p2 = 0.052 n2 =100
if we estimate with 90% confidence the difference in population proportions, what would be the outome?

you can apply the binomial method directly which can be tedious and difficult
or "if" the assumptions are met, can apply a normal approximation to the binomial.

The enable the use of the normal approximation, the following need to be met
1. and and and

you provided p1 = 0.48 n1 = 100 p2 = 0.052 n2 =100
NOTE: not sure if your p2 is correct. Nevertheless, it looks like the requirements above are met.

90% confidence interval for difference in the population proportions yields Z=1.645
