Answer 1

EXPLANATION:

We are given a set of numbers that represent the number of customers who shopped at a pet store everyday.

The numbers are as follows;

$42,35,56,29,42,39,23$

The mean (or average) of a given data set is calculated as shown by the formula below;

$Mean=\frac{\Sigma x}{n}$

Where the variables are;

$\begin{gathered} \Sigma=summation \\ x=individual\text{ }data \\ n=number\text{ }of\text{ }data \end{gathered}$

We will now substitute the values given into the formula;

$Mean=\frac{42+35+56+29+42+39+23}{7}$$Mean=\frac{266}{7}$$Mean=38$

ANSWER:

The mean number of customers is 38.

The correct answer is option B
