You can put this solution on YOUR website! What are the critical values that correspond to a 95% confidence level and a sample size of 93?
-----
The z-values are -1.96 and +1.96
-----
You need more information about the standard deviation
of the population, viz. s.
---
Then the standard deviation of the means of all samples of
of size 3 will be s/sqrt(3).
---
And the 95% critical values will be -1.96(s/sqrt(3)) and +1.96(s/sqrt(3))
