Question 1046798: 1. Say I take a random sample and all I know is the mean and standard deviation for that sample.
How would I estimate the population mean?
2. How do I know if a confidence interval is appropriate to use? Does a scenario have to meet a certain criteria?

An example that may help to clarify Your questions
A sample of 89 golfers showed that their average score on a particular golf course was 90.98
with a standard deviation of 6.47.
and state the final answer to at least two decimal places.):
-------------------
x=bar = 90.98
(A) Find the 98% confidence interval of the mean score for all 89 golfers.
ME = 2.3263[6.47/sqrt(89)] = 1.5955
-----
CI: 90.98-1.5955 < u < 90.98+1.5955
CI: 89.3845 < u < 92.5755
