Question

The effect of phosphate supplementation on bone formation was assessed in six healthy dogs. For each dog, bone formation was measured for a 12-week period of phosphate supplementation as well as for a prior 12-week control period.

Dog	1	2	3	4	5	6
Control	1.73	3.37	3.59	2.05	1.86	3.6
Phosphate	8.16	4.48	3.98	5.24	3.04	7.03

Test the claim that there is a significant difference in bone formation between the control time period and the phosphate supplementation time period. Use α = 0.10.
