The manager of a pizza chain in Albuquerque, New Mexico, wants to determine the average size of their advertised 20-inch pizzas.
7nadin3 [17]

Answer:

The sample must be of at least 48 pizzas.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

How large a sample must she take if she wants the margin of error to be under 0.5 inch?

She needs a sample of at least n, in which is found when M = 0.5, \sigma = 2.1

M = z*\frac{\sigma}{\sqrt{n}}

0.5 = 1.645*\frac{2.1}{\sqrt{n}}

0.5\sqrt{n} = 2.1*1.645

\sqrt{n} = \frac{2.1*1.645}{0.5}

(\sqrt{n})^{2} = (\frac{2.1*1.645}{0.5})^{2}

n = 47.73

Rounding up

The sample must be of at least 48 pizzas.
