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. The magazine surveyed Standard Air (population 1) and Down Under airlines (population 2). Standard Air lost 45 out of 600 bags. Down Under airlines lost 25 of 450 bags. Does Standard Air have a higher population proportion of lost bags on international flights? Which of the following is the appropriate p-value? Group of answer choices 0.1056 0.1634 0.0817 0.8366 Please step by step answer.
