Apologies I typed in the wrong figures. If the normality tests have shown one variable to be 0.18 and the other .522 should I assume normality or not?

Also having conducted a t test should I decide on significant using the 2 tailed significant p value? Sorry to sound really clueless.

Thanks

Thanks

Is it directional, like this (requires the one-tail prob):

Ho: mu1 = mu2

Ha: mu1 > mu2

or is it non-directional, like this (requires the two-tail prob):

Ho: mu1 = mu2

Ha: mu1 not= mu2
