1-If testing the difference between two population proportions under independent sampling, you pool the sample proportions and compute as p=(x1+x2/ (n1+n2). Group of answer choices if the population proportions are assumed equal if the difference in the population proportions is hypothesized to be different than zero All of these choices are correct if the difference in the population proportions is hypothesized to be zero. 2-A consumer magazine wants to figure out which of two major airlines lost a higher proportion of luggage on international flights.
