Answer 2

Answer:

1.2

Step-by-step explanation:

Given : A small business has an average income of $3,000.00 per month with a standard deviation of $250.00.

To Find :  If the income in a given month is $3,300.00, what z-score corresponds to this value?

Solution:

Formula of z score $z=\frac{x-\mu}{\sigma}$

x = 3300

$\mu = 3000$

$\sigma = 250$

Substitute teh values in teh formula

$z=\frac{3300-3000}{250}$

$z=1.2$

Hence  z-score corresponds to this value is 1.2
