Question:

Mancini's Pizzeria sells four types of pizza crust. Last week, the owner tracked the number sold of each type, and this is what he found.

Type of Crust Number Sold

Thin crust          312

Thick crust          245

Stuffed crust          179

Pan style                  304

Based on this information, of the next  4500 pizzas he sells, how many should he expect to be thick crust? Round your answer to the nearest whole number. Do not round any intermediate calculations.

Answer:

1060 thick crusts

Step-by-step explanation:

Given

The above table

Required

Expected number of thick crust for the next 4500

For last week data, calculate the proportion of thick crust sold

$\hat p = \frac{Thick\ crust}{Total}$

$\hat p = \frac{245}{312+245+179+304}$

$\hat p = \frac{245}{1040}$

$\hat p = 0.235577$

For the next 4500;

$n = 4500$

The expected number of thick crust is (E(x)):

$E(x) = \hat p * n$

$E(x) = 0.235577 * 4500$

$E(x) = 1060.0965$

$E(x) \approx 1060$
