Assume that you have a sample of n1=9​, with the sample mean Upper X overbar 1 equals =50​, and a sample standard deviation of Upper S 1 equals =6, and you have an independent sample of n2=12 from another population with a sample mean of Upper X overbar 2 equals =39 and the sample standard deviation Upper S 2 =5.

Complete parts below:

1.) what is the tSTAT?

2.) what is the degrees of freedom?

3.) what is the critical value?

4.) what is your statistical decision?
