Don4, I'm trying to understand what it is you are asking. Are you referring to the Metallurgy and Materials PE examination?

Try the following: t=(x[1,ave]-(x[2,ave])/(s[p]*sqrt(1/n1+1/n2)) S[p]^2=((n1-1)*s1^2+(n2-1)*s2^2)/(n1+n2-2) Take the sqrt of that to get s[p] Should be something like: t= (.759/.749875)/(.00987*.5) = 1.85 To tell if the hypothesis is rejected or not, you need to compare the value and degrees of...
