An advocacy organization surveys 873 citizens of country A and 185 of them reported being born in another country. Similarly, 229 out of 841 citizens of country B reported being foreign-born. The researchers want to test if the proportions of foreign born are the same in country B as in country A. Complete parts a through e below. a) What is the difference in the sample proportions, ModifyingAbove p with caret 1 minus ModifyingAbove p with caret 2, of foreign born residents from both countries? Assume ModifyingAbove p with caret 1 is the proportion of foreign born residents from country A and ModifyingAbove p with caret 2 is the proportion of foreign born residents from country B. The difference in the sample proportions, ModifyingAbove p with caret 1 minus ModifyingAbove p with caret 2, is negative 0.060. (Round to three decimal places as needed.) b) What is the pooled proportion of foreign born in both countries combined? The pooled proportion of foreign born in both countries combined is
