Assignment Help Basic Statistics
Reference no: EM131752829

Question: Medicine and Clinical Studies The diameter of a virus is approximately 0.3 mm (micrometers). There is some speculation that new virus strains exhibit greater variability in diameter. A medical research lab obtained a random sample of 15 new virus strains and measured the diameter (in mm) of each. The sample mean diameter was 0.323 and the sample variance was s2 = 0.0026. Is there any evidence to suggest the true population variation in diameter of viruses has increased from 0.0015? Assume normality and use a = 0.05.
