00:01 Okay, so we've got some data here about score before taking a drug, score after taking a drug, and we want to see if the drug improves the score or not.

00:13 So part one asks is this a one -tailed or a two -tailed test? well if we're testing to see whether it improves the score, then our null hypothesis, i know it asks for this later, but in order to find whether it's one or two -tailed we need to write these down.

00:28 So the null hypothesis is going to be that the difference d is zero, and the alternative hypothesis is going to be that the difference d is less than zero, i .e.

00:42 Because we're defining d is the score before minus the score after, so if we want the score after to be bigger then d must be negative.

00:50 And because this is a less than sign and not a not equal to sign it's going to be a one -tailed test.

01:00 This is going to be our rejection region over here.

01:03 So the answer to part one is going to be one -tailed.

01:09 Part two asks us to write a new column with the differences, so we can do that quite easily.

01:16 So the first difference is given by seven minus five, sorry it's given by five minus seven, they do x minus y, so that's minus two.

01:25 For patient bb it's six minus eight, which is again minus two.

01:29 For patient cc, six minus six is zero.

01:31 Dd, four minus four is zero.

01:34 Ee, three minus five is minus two.

01:37 And ff, four minus five is minus one...
