04: The mean level of prothrombin in the Iraqi population is known to be approximately 20 mg/ 100 ml and the standard deviation is 4mg/ 100 ml. A sample of 40 patients from Thi- Oar Province showing vitamin K deficiency has a mean prothrombin level of 18.5 mg/ 100 ml. How reasonable is it to assume that the true mean for Thi-Qar patients with Vitamin K deficiency is the same as that for the normal population?
