QuestionFind the mean of the following numbers: 28, 40, 53, 39, 45.

Studdy Solution

STEP 1

Assumptions1. The data set is {28,40,53,39,45} . We are calculating the arithmetic mean, which is the sum of all the numbers divided by the count of the numbers.

STEP 2

First, we need to find the sum of all the numbers in the data set.
$Sum =28 +40 +53 +39 +45$

STEP 3

Calculate the sum of the numbers.
$Sum =28 +40 +53 +39 +45 =205$

STEP 4

Now that we have the sum of the numbers, we can find the count of the numbers in the data set. In this case, there are numbers.
$Count =$

STEP 5

Now we can calculate the mean by dividing the sum by the count.
$Mean = Sum / Count$

STEP 6

Plug in the values for the sum and the count to calculate the mean.
$Mean =205 /5$

STEP 7

Calculate the mean.
$Mean =205 /5 =41$ The mean of the data set is41.
