Researchers examined the effect of phosphate supplementation on bone formation in six healthy adult dogs. For each dog, bone formation was measured twice: once after 12 weeks of phosphate supplementation and once after a 12-week control period. The results in percent bone growth per year are shown below. Does the data provide evidence that phosphate supplementation significantly stimulates bone formation at 1% significance level? (Follow the 5-step)
