Assuming that the population is normallydistributed, construct a 90% confidence interval for the population mean for each of the samples below. Explain why these two samples produce different confidence intervals even though they have the same mean and range.

SampleA:

12336678

SampleB:

12345678

Construct a 90% confidence interval for the population mean for sample A.
