In hypothesis testing the claim that we have to test always goes into alternative hypothesis. The null hypothesis is negation of claim.
Here the claim to be tested is James bond can taste the difference between a martini that is shaken and one that is stirred.
So negation of this claim is James bond can not taste the difference between a martini that is shaken and one that is stirred.
