Verified Answer :

1.  The answer is 1000.  The ratio of chocolate to others is \(\frac{2}{3}\) in the small sample size, so in the larger one, it should be the same ratio.  So you do \(\frac{2}{3} * 1500 = 1000\)

2. 
The answer is 0.  The range is the difference between the smallest and largest value for each whisker.  They're both 40, so \(40-40 = 0\)
