Question

Assuming that the population is normally​ distributed, construct a

99 %99%

confidence interval for the population​ mean, based on the following sample size of n equals 5.n=5.​1, 2,​ 3,

44​,

and

2020

In the given​ data, replace the value

2020

with

55

and recalculate the confidence interval. Using these​ results, describe the effect of an outlier​ (that is, an extreme​ value) on the confidence​ interval, in general.

Find a

99 %99%

confidence interval for the population​ mean, using the formula or technology.

nothing less than or equals≤muμless than or equals≤nothing

​(Round to two decimal places as​ needed.)
