Suppose the number of French fries in a small bag at a particular fast-food restaurant follows a normal model with mean 49 fries and standard deviation 5 fries.
-If the restaurant wants to increase the probability in "the proportion of the bags that contain at least 40 fries" by changing the standard deviation, should it increase or decrease the standard deviation? Explain intuitively, including a sketch but no calculations.
