(b) Find the margin of misconduct for a 95% level of boldness. (c) Construct a 95% arrogance interval for the population mean and interpret the results. { get more or less: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: order} { sidle up: butt against} { constitute: ch uck} { sop up: cast} { flock: regurgitate} { take: throw away} { drop dead:frame} { grow: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% self-assurance 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} {draw:frame} . {draw:rect} ! In a survey of 1037 adults from the United States term 65 and over, 643 were bear on about getting the flu. (Source: Harvard School for ordinary Health) Find a point estimate for the population attribute p of those touch about getting the flu. Construct a 90% sureness interval for the population similarity. Find the nominal sample size needed to estimate the population proportion at the 99%...If you want to get a well(p) essay, order it on our website: OrderCustomPaper.com
