The statistics of n=22 and s=14.3 result in this 95% confidence interval estimate of σ: 11.0

The statistics of

n=22

and

s=14.3

result in this 95% confidence interval estimate of

σ:

11.0<><>

That confidence interval can also be expressed as (11.0, 20.4). Given that

15.7±4.7

results in values of 11.0 and 20.4, can the confidence interval be expressed as

15.7±4.7

as well?

Choose the correct answer below.

Yes. In general, a confidence interval for

has s at the center.

No. The format implies that

s=15.7,

but s is given as 14.3. In general, a confidence interval for

does not have s at the center.

Yes. Since the chi-square distribution is symmetric, a confidence interval for

can be expressed as

15.7±4.7.
