Question

The shoe size for all the pairs of shoes in a person closet are recorded. what is the mean

Answer 1

The mean size of the shoe is 7.

Explanation:

We are given the shoe size for all the pairs of shoes in a person closet below;

X = 7, 7, 7, 7, 7, 7, 7, 7, 7, 7.

And we have to find the mean of the data.

Let X = shoe size for all the pairs of shoes

As we know that the mean of any discrete data is given by the following formula;

Mean,
`\bar X` =
`\frac{\text{Sum of all the observations}}{\text{Total number of observations}}`

Here, the number of observations = 10

=
`(7+7+7+7+7+7+7+7+7+7)/(10)`

=
`(70)/(10)` = 7

Hence, the mean size of the shoe is 7.
