In a recent research poll, 83.4% of 500 randomly selected men in the U. S. knew the name of our current vice president. When 500 randomly selected women in the U. S. were asked, 79% knew the vice president’s name.

(a) Construct and interpret a 95% confidence interval for the true difference in the proportion of U. S. men and the proportion of U. S. women who know the name of our current vice president.

(b) Based on this confidence interval, is there convincing evidence that the true proportion of men who know the name of the current vice president is different than the true proportion of women that know the name the current vice president? Explain.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

the correct answer is x/3+10≥32

hope this !
