Statistics - Find Significant value?

Question

Here is some statistics from a study.

Mean = 13

standard deviation = 3.3

Subjects (n) = 24

If another study was done, what value of mean would be considered

statistically different from 13 at 95% CI?

Indicate method please.

Thanks

Answer 1

ANSWER: Indeterminate.

Why?

"statistically different" dependent on SAMPLE MEAN, SAMPLE STANDARD DEVIATION and SAMPLE SIZE.

"statistically different from 13 at 95% CI" cannot be determined without knowledge of SAMPLE MEAN, SAMPLE STANDARD DEVIATION and SAMPLE SIZE from "another study".
