A random sample has been taken from a population. A statistician, using this sample, needs to decide whether to construct a 92% confidence interval for the population mean or a 98% confidence interval for the population mean. How will these intervals differ?

  1. The wider interval is dependent on a larger sample size.
  2. The wider interval is dependent on whether the sample is unbiased.
  3. The wider interval is dependent on whether a z statistic or a t statistic is used.
  4. The 92% confidence interval will be wider than the 98% confidence interval.
  5. The 92% confidence interval will not be as wide as the 98% confidence interval.
