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 are shown below. Do the data provide
evidence that phosphate supplementation significantly stimulates
bone formation?...
