5.4 unexpected expense. in a random sample 765 adults in the united states, 322 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? (b) what parameter is being estimated? (c) what is the point estimate for the parameter? (d) what is the name of the statistic can we use to measure the uncertainty of the point estimate? (e) compute the value from part (d) for this context. (f) a cable news pundit thinks the value is actually 50%. should she be surprised by the data? (g) suppose the true population value was found to be 40%. if we use this proportion to recompute the value in part (e) using p = 0.4 instead of ˆp, does the resulting value change much?
