Mean 47.281

Stand. E 1.615

Stand. D 11.53

Count (N?) 51

I estimated the 95% confidence interval for the mean salary for male faculty members to be $44,037 to $50,526.

Given this data (female):

Mean 43.195

Stand. E 1.16

Stand. D 10.636

Count (N?) 83

How do I find critical t-values for 90% and 95% CI?

How do I calculate the standard error for the mean salary in pop. of female?

How do i find upper and lower bounds of the 90% and 95% CI for the mean salary in pop. of female?

(I realize alot of questions, I need a starting point...the help with the z-scores was fantastic)
