In a recent Pew Research Poll, 287 out of 522 randomly selected men in the U. S. were able to identify Egypt when it was highlighted on a map of the Middle East. When 520 randomly selected women were asked, 233 were able to do so. A) Find the standard deviation of the sampling distribution to the nearest thousandth.

B) Construct and interpret a 95% confidence interval for the difference in the proportions of U. S. men and women who can identify Egypt on a map. Round to the thousandth place.

C) Test the claim that there is a difference in these 2 proportions at the 0.05 level. Identify the hypotheses, P-value, and the conclusion in the context of the problem.

Astudent solves the equation for v. start with the original equation. use the square root property. use the division property of equality. use the multiplication property of equality. simplify. which statement explains how to correct the error that was made? the square root property must be applied after all other properties of equality are applied. the multiplication property of equality should have been applied before the division property of equality. the division property of equality should have been applied to move the fraction to the other side of the equation. the square root property should have been applied to both complete sides of the equation instead of to select variables.
