practice volumn 2 page123 question 69 Can null hypothesis be: Ho: b2 = 0. And the alternative hypothesis is: HA: b2 < 0 I thought Ho and Ha must cover from –infinity to +infinity?
anyone helps me with my confusion? I feel like the answer is wrong, we can’t define Hnull=0 and Ha<0, What do u guys think? orangeyt Wrote: ------------------------------------------------------- > practice volumn 2 > page123 > question 69 > > Can null hypothesis be: Ho: b2 = 0.

if Ho = 0 then Ha does not equal zero. It looks like this =/ if you could put one on top of the other.
