Explain why these two samples produce different confidence intervals

  

Assuming that the population is normally distributed, construct a 95% confidence interval estimate for the population mean for each of the following samples: Sample A: 1 1 1 1 8 8 8 8 Sample B: 1 2 3 4 5 6 7 8 Explain why these two samples produce different confidence intervals even though they have the same mean and range.
