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.)

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.
Find a 95 % confidence interval for the population mean, using
the formula or technology.

Assuming that the population is normally distributed, construct
a 90 % confidence interval for the population mean, based on the
following sample size of n equals 6. 1, 2, 3, 4 comma 5, and 30
In the given data, replace the value 30 with 6 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 90 % confidence interval for the

#1. You are to construct a
99% confidence interval of a normally distributed population; the
population standard deviation is known to be 25. A random sample of
size 28 is taken; (i) the sample mean is found to 76 and (ii) the
sample standard deviation was found to be 30. Construct the
Confidence interval. Clearly name the standard distribution you
used (z, or t or F etc.) and show work. (10 points)
