SAT Question 57481175: Distributions, Center & Spread answer and explanation with Desmos solution

Choice B is correct. It's given that the bar graph shows the number of each type of monkey in a sanctuary. The bar representing the number of mandrills has a height of $5$; therefore, there are $5$ mandrills in the sanctuary. The bar representing vervets has a height of $11$; therefore, there are $11$ vervets in the sanctuary. Therefore, there are $11-5$, or $6$, more vervets in this sanctuary than mandrills.
