Hey all! So I should have looked at this earlier, but I haven't...

So there's a bit of data manipulation that's gotta take place: log changes, stacking and unstacking of data, etc..

Went through it quickly today in minitab: more or less, (according to 2-sample T's) there're significant differences in both, right? Normality's a bit fuzzy sometimes, along with equal variances but logs fix that up a couple of times... There's an outlier in at least the Mobile phone spending (and I vaguely remember one from the other, too, which could be 40 instead of 400?) which is removed without many changes to normality or end results..

...missed anything? Am I just totally running in the wrong direction?
