A veterinarian finds that weights for the population of each dog breed tend to be approximately normally distributed. They know that the mean weight of beagles is 25 pounds with a standard deviation of 3 pounds. The mean weight for Great Danes is 150 pounds with a standard deviation of 20 pounds. The veterinarian finds that about 68% of beagles weigh between 22 and 28 pounds. What can this tell us about Great Danes? Explain your reasoning.
