A pizza shop sells pizzas in four different sizes. The 1000 most recent orders for a single pizza gave the following proportions for the various sizes:
With x denoting the size of a pizza in a single-pizza order, the given table is an approximation to the population distribution of x.
a. Construct a relative frequency histogram to represent the approximate distribution of this variable.
b. Approximate P(x < 16).
c. Approximate P(x ≤16).
d. It can be shown that the mean value of x is approximately 14.8 inches. What is the approximate probability that x is within 2 inches of this mean value?
