  • If we took repeated samples, approximately 90% of the samples would produce the same confidence interval. b. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean.
  • If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean.
  • If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples.
