H0 : u = 8500
H1 : u > 8500
Step-by-step explanation:
Given:
sample size, n = 350
mean, u = 8500
Sample mean, x' = 8745
Standard deviation = 1,200
Level of significance = 0.05
In this case, the financial administrator believes that the average cost of tution, room and board at small liberal arts colleges is higher than the reported $8500. We can say this is the alternative hypoyhesis, since it is a claim.

H0 : u = 8500
H1 : u > 8500
