So will that make it so .001 will always be 2.33 on the z-table?

since we are to assume that the null hypothesis is true, then why is the null hypothesis here “Drug doesn’t work” and not drug does work

Neeraj Rajasekar

Standard convention is to put the unremarkable, boring, all-is-equal, etc on the Null Hypothesis. In this case, drug doesn't work is a better fit.

Why is the statement saying an Oreo is 11.3g a null hypothesis and not alt?

Sarah Meier

48:14

Because that is the oreos=11.3g, and the equal signs always go in the null

I thought the the null always need the equal sign?

Neeraj Rajasekar

01:07:02

"Equal sign" includes greater than / equal to (the < with a a line below it)

Ian M Gullickson

01:07:06

It does in this case, since “less than or equal to” contains equal

If we fail to reject, does this mean the evidence is not sufficient
