Question

The serum calcium concentrations of seven patients with hypoparathyroidism are compared with those of seven healthy patients. The seven patients with the disease showed calcium levels of 8.12, 7.98, 8.06, 8.20, 8.08, 8.15, 8.22 mg/dL, while the seven healthy patients showed calcium levels of 8.82, 8.91, 9.23, 10.02, 9.67, 9.34, 9.41 mg/dL. Is there a significant difference in the variance of serum calcium concentration for these two groups? Which t test must be used? Is there a significant difference in the average serum calcium concentration for these two groups?

Explanation / Answer

Ans) There is a significant difference between the variance of healthy and patients with disease given as below:

Variance of Healthy= 0.173924

Variance of Diseases patients= 0.006995

Average of Healthy= 9.342857

Average of Diseases patients= 8.115714

Independent sample t test can be used.

D H 8.12 8.82 7.98 8.91 8.06 9.23 8.2 10.02 8.08 9.67 8.15 9.34 8.22 9.41
