A survey asked, "Do you think that homeless people are responsible for the situation they are in?" Of the 2,507 Americans surveyed, 1,404 said no. (a) Determine the sample proportion of Americans who think that homeless people are not responsible for the situation they are in. (Round your answer to the nearest whole number.) Sample proportion is   % (b) With an 80% level of confidence, find the margin of error (MOE) associated with the sample proportion. (Give the answer to one decimal place, if needed.) MOE =  % (c) With a 95% level of confidence, find the margin of error (MOE) associated with the sample proportion. (Give the answer to one decimal place, if needed.) MOE =  % (d) The answer in part (c) is smaller than or larger than    the answer in part (b). Why? In order to guarantee 95% accuracy, we must increase or decrease    the error.

(a) Determine the sample proportion of Americans who think that homeless people are not responsible for the situation they are in. (Round your answer to the nearest whole number.)
Sample proportion is   %

(b) With an 80% level of confidence, find the margin of error (MOE) associated with the sample proportion. (Give the answer to one decimal place, if needed.)
MOE =  %

(c) With a 95% level of confidence, find the margin of error (MOE) associated with the sample proportion. (Give the answer to one decimal place, if needed.)
MOE =  %

(d) The answer in part (c) is smaller than or larger than    the answer in part (b). Why?
In order to guarantee 95% accuracy, we must increase or decrease    the error.
