Transcribed Image Text:Assuming that the population is normally distributed, construct a 95% 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.
Sample A: 1 1 2 3 6 7 8 8
Sample B: 1 2 3 4 5 6 7 8
O Full data set
Construct a 95% confidence interval for the population mean for sample A.
OSus
(Type integers or decimals rounded to two decimal places as needed.)
Construct a 95% confidence interval for the population mean for sample B.
(Type integers or decimals rounded to two decimal places as needed.)
Explain why these two samples produce different confidence intervals even though they have the same mean and
range.
O A. The samples produce different confidence intervals because their standard deviations are different.
O B. The samples produce different confidence intervals because their critical values are different.
O C. The samples produce different confidence intervals because their medians are different.
O D. The samples produce different confidence intervals because their sample sizes are different.
