Question 184266: Hi,
This is not from a book, can you please tell me if I am on the right track?:
The appropriate "null hypothesis" for a lower-tail test to determine if mean body weight of all the women who have joined a health club is less than 150 pounds would be
a. H0: (Mu)greater than or equal to 150 lb.
b. H0: (Mu) < 150 lb.
c. H0: (Mu) = 150 lb.
d. H0: (Mu)not equal to 150 lb.
*I was thinking (a.), is this the correct answer?
If not can you please explain why, and which one would be the best answer?
Thank you
You can put this solution on YOUR website! The appropriate "null hypothesis" for a lower-tail test to determine if mean body weight of all the women who have joined a health club is less than 150 pounds would be
a. H0: (Mu)greater than or equal to 150 lb.
b. H0: (Mu) < 150 lb.
c. H0: (Mu) = 150 lb.
d. H0: (Mu)not equal to 150 lb.
*I was thinking (a.), is this the correct answer?
-------------------
It depends on your textbook and/or you instructor.
Some books would say "a" is the answer ; some
would say "c" is the answer ; and still others
would say "a" or "c" is the answer.

I have seen both choices used.
