In a random sample 767 adults in the United States, 327 say they could not cover a $400 unexpected expense without borrowing money or going into debt. (a) What population is under consideration in the data set? all adults who were surveyed all adults in the United States who could cover the expense all adults all adults in the United States all adults in the United States who could not cover the expense (b) What parameter is being estimated? the proportion of U.S. adults who could cover a $400 expense without borrowing money or going into debt the exact number of U.S. aduits who could not cover a $400 expense without borrowing money or going into debt the proportion of U.S. adults who could not cover a $400 expense without borrowing maney or going into debt. the average number of U.S. adults who could cover h 3400 expense without borrowing money or going into debt the average number of U.S. adults who could not cover a 1400 expense without borrowing money or going into debt (c) What is the point estimate for the parameter? (Round your answer to three decimal places.) standard error sample mean (c) Compute the value from part (d) for this context. (Round your answer to four decimal places.) x (t) A cable news punct thinks the value is actualiy so\%, Shouid she be surprised by the data? (Round your answer to two decimal places.) A value of 0.50 is tandard errors way from the poimt estimate, so she \& be surpeised. (9) Suppose the true population value was found to be 40m. If we use this propertion to recompute the value if part (e) using =0.4 instead p, does the resulting value change much)
