Eight patients are treated for hypoparathyroidism using a drug therapy. Before the treatment, the eight patients had serum calcium levels of 8.12, 7.98, 8.06, 7.65, 8.20, 8.08, 8.15, and 8.22 mg/dL. After treatment, their serum levels were 8.22, 8.02, 8.08, 7.96, 8.31, 8.28, 8.20, and 8.33 mg/dL. Was there a significant increase in serum calcium after the patients were given the treatment? Which t test should be used to answer this question?
