B h0 p0 c h0μ1253 d ha μ0 be careful because we took

b. H0: p=0
c. H0:μ=125.3
d. Ha: μ>0
Be careful. Because we took a difference as "before" minus "after" we want to see if the
difference is negative not positive.
e. Ha:μ<0
f. H0:μ≠0
g. Ha:μ≠125.7
h. Ha:μ≠0
i. Ha:μ>125.7
j. Ha:μ<125.7
k. Ha:p≠0
l. Ha:p>0
The correct answers are: H0:μ=0, Ha:μ<0
