A researcher is interested in finding a 95% confidence interval for the
. With 95% confidence the population mean minutes of concentration is between ? and ? minutes.
c. If many groups of 140 randomly selected members are studied, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population mean minutes of concentration and about ?percent will not contain the true population mean minutes of concentration.
