Question

Problem 3: Foreign Policy (17 pts) One hundred thirty-five citizens were selected at random and were asked to state their opinion regarding U.S. foreign policy. Forty-three were opposed to the foreign policy. After several weeks, during which they received an informative newsletter, they were again asked their opinion; 37 were opposed, and 30 of the 37 were persons who originally were not opposed to the U.S. foreign policy. Is the change in numbers of people opposed to the U.S. foreign policy significant? i. (9 pts) Perform the test "by hand" ii. (8 pts) Perform the test "using a software library"

“by hand” means you utilize quantile/distribution tables, and/or Gaussian approximations, as appropriate, and otherwise do all of your calculations with pen and paper (and a calculator)“using a software library” means you can feed your data into a built-in function, like t.test and binom.test in R, and interpret the output as appropriate.
