* Sample Size is 12 and level of confidence 95%
Degrees of freedom = Sample Size - 1 = 12 -1 = 11
t -value for Degrees of freedom 11 and 95% level of confidence is 2.201
* Sample Size is 20 and level of confidence is 90%
Degrees of freedom = Sample Size - 1 = 20 -1 = 19
t - value for Degrees of freedom 19 and 90% level of confidence is 1.729
* Sample Size is 8 and Level of confidence is 99%
Degrees of freedom = Sample size -1 = 8 -1 = 7
t -value for Degrees of freedom 7 and 99% level of confidence is 3.500
