It is knоwn thаt the pоpulаtiоn vаriance equals 484. With a 0.95 probability, the sample size that needs to be taken to estimate the population mean if the desired margin of error is 5 or less is ____________. Refer to the following formula and table. σ x = σ n z = x - μ σ x Standard Error = σ n Margin of Error = z α / 2 * σ n Confidence Interval = x ± z α / 2 * σ n n= ( z * σ m a r g i n o f e r r o r ) 2 z dsistribution table from 0.0 to 2.49.jpg
