Assume you have a sample of n1=8, with a sample mean x1= 42 and a sample standard deviation, s1 = 4 and an independent sample of n2=15 from another population with a sample mean of x2=34 and a sample standard deviation of s2 = 34. the pooled variance, sp 2 = 776.

b. in finding the critical value, how many degrees of freedom are there?
c. what is your statistical decision?
