An experiment is conducted to test the claim that james bond can taste the difference between a martini that is shaken and one t

sammy [17]

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.

So the null hypothesis for given experiment is

Null hypothesis: James bond can not taste the difference between a martini that is shaken and one that is stirred.

Alternative hypothesis: James bond can taste the difference between a martini that us shaken and one that is stirred.

"Over" usually means divide. First hint, check.

If we write it out, it looks like this:

$\frac{y}{7}$

This is the same as <em>some number divided by 7.</em>
