1. The answer is 1000. The ratio of chocolate to others is [tex]\frac{2}{3}[/tex] in the small sample size, so in the larger one, it should be the same ratio. So you do [tex]\frac{2}{3} * 1500 = 1000[/tex]
2. The answer is 0. The range is the difference between the smallest and largest value for each whisker. They're both 40, so [tex]40-40 = 0[/tex]
