Two researchers want to compare the variability of the boiling temperature of object A and object B. Previous study shows that object A's boiling temperature is normally distributed with mean temperature of 100°C while object B's boiling temperature is normally distributed with mean temperature of 100°F. They collected a sample of 50 for each type and measured the boiling temperature using degrees Centigrade. Suppose the standard deviation of the boiling temperature of object A and object B are 50 and 10 respectively, can we say that the boiling temperature of object A is more varied than that of object B?
