ou are doing a problem where you have a negative z-score, and you have to look up the proportion of the shaded area in the tail beyond that z-score; in other words, you are shading to the left from your z-score, and looking for the proportion that you shaded. Four “proportions” are given below. Which one is the ONLY one that could potentially be the number you are looking for? (Hint: Think about what you know about proportions: What kind of number are they? And what things can they represent?) Group of answer choices p = 0.3800 p = -0.1500 p = 1.1500 p = 0.5635

advocacy organization surveys 966 citizens of country A and 186 of them reported being born in another country. Similarly, 177 out of 1213 citizens of country B reported being foreign-born. The researchers want to test if the proportions of foreign born are the e in country B as in country A. Complete parts a through c below. What is the difference in the sample proportions, p, - p2, of foreign born residents from both countries? Assume p, is the proportion of foreign born residents from country A and p, is the proportion of foreign born residents from country B. difference in the sample proportions, p1-P2, is und to three decimal places as needed )
