For each level of confidence c below, determine the corresponding normal confidence interval. assume each confidence interval is constructed for the same sample statistics.

a) with

Since this represent the second largest width interval needs to represent the c=0.95 or 95% confidence interval.

b) with

Since this represent the largest width interval needs to represent the c=0.99 or 99% confidence interval.

c) with

Since this represent the smallest width interval needs to represent the c=0.99 or 88% confidence interval.

d) with

Since this represent the third largest width interval needs to represent the c=0.90 or 90% confidence interval.

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

represent the sample mean for the sample  

population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size  

Solution to the problem

The confidence levels provided are :

c=0.88, c=0.90, c=0.95, c =0.99

And we need to associate each confidence level with the interval

We have the following intervals:

a) with

We can find the width of the interval like this:

Since this represent the second largest width interval needs to represent the c=0.95 or 95% confidence interval.

b) with

We can find the width of the interval like this:

Since this represent the largest width interval needs to represent the c=0.99 or 99% confidence interval.

c) with

We can find the width of the interval like this:

Since this represent the smallest width interval needs to represent the c=0.99 or 88% confidence interval.

d) with

We can find the width of the interval like this:

Since this represent the third largest width interval needs to represent the c=0.90 or 90% confidence interval.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
