For confidence interval for the mean of a normal distribution, or the difference between two means, we use the student's-t distribution if :
The standard deviation(s) is(are) known
The standard deviation(s) is(are) not known
We don't use it
No one of the above choices
A sample consist of 10 measurements, the confidence interval of the mean has to be calculated with a 95 % confidence level. If the standard deviation is not known, what are the parameters α/2 (alpha/2) and ν of the student's-t distribution :
0.025 ; 10
0.025 ; 9
0.05 ; 10
0.05 ; 9
