Question

Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n=8.

1, 2, 3, 4, 5, 6, 7 and 16

In the given data, replace the value 16 with 8 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 95% confidence interval for the population mean, using the formula or technology.

___≤ μ ≤ ___

(Round to two decimal places as needed.)

Answer #1

Assuming that the population is normally distributed, construct
a 95 % confidence interval for the population mean, based on the
following sample size of n equals 5.n=5.
1,2,3,4 and 17
In the given data, replace the value 17 with 5 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.
