(b) Find the margin of misconduct for a 95% level of boldness. (c) Construct a 95% cartel interval for the population mean and interpret the results. { get round:rect} solvent: The point estimate of the population mean is computed as: { back down: butt} { nurse: assign} (b) By definition, the margin of demerit is computed as: { drop dead: place} { sidle up: butt against} { constitute: chuck} { seize on: spue} { caboodle: ready} { pile: cat} { weave:frame} { hap:frame} {draw:frame} {draw:frame} Also, standard deviation {draw:frame} {draw:frame} {draw:frame} {draw:frame} {draw:frame} This means that: Margin of error = 2.0395*(24.72242/√30) = 9.205709 (c) The 95% assumption interval is computed as: {draw:frame} {draw:frame} {draw:frame} {draw:frame} {draw:frame} = (88.90429, 107.
3157) {draw:frame} {draw:frame} This means that theres a 95% chance that the interval (88.90429, 107.3157) contains the material population mean {draw:frame} {draw:frame} {draw:frame} {draw:frame} {dr aw:frame} . {draw:rect} In a su! rvey of 1037 adults from the United States term 65 and over, 643 were pertain about getting the flu.
