Question
5. The ventricle is the cavity in the brain. The
elderly is 38.3 cm3. We know that the ventricular volume is
the volume of ventricle as a biomarker for Alzheimer’s disease, we collected the ventricular
volumes of 25 Alzheimer’s disease patients. If their sample mean was 49.9 cm3 with a sample
standard deviation of s=25.3 cm3. Can we conclude that the mean ventricular volume of
Alzheimer’s disease patients is not equal to 38.3 cm3? Use the significance level of 5%.
