Period. If we reject it we ana= lyze the factors and try to find why population A has a higher proportion o= f people producing a working program, have a microwave oven or why people l= iving=20 in Miami are more likely to have visited Disneyland than people living in M= elbourne In our case we could think that since the course was an elective one, "wr= ite first and think later" or "clever trick" programmers flocked to the co= urse during the C years and deserted it during the Ada years. One of such programmers in a group working on a com= plex=20 project like this could wreak havoc. This is definitely not random and wou= ld have to be investigated along with the hypothesis that the Ada programme= rs were initially similar but the contact with Ada not only the language bu= t also the litterature (compare the Barnes books agaisnt the compendium of = clver trickjs that is the K&R C book) turned them into serious, comment lov= ing, cheap trick adverting, software engineer types.
