(b) Find the margin of misconduct for a 95% level of boldness. (c) Construct a 95% authorization interval for the population mean and interpret the results. { get well-nigh: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: commit} { sidle up: butt against} { constitute: chuck} { redact: compose} { slew: swan} { key: soma} { weave:frame} { race: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% trustfulness 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:f rame} {draw:frame} . {draw:rect} !
