QuestionFind the mean and median of Mike's contributions: \$50, \$80, \$60, \$50, and \$90.

Studdy Solution

STEP 1

Assumptions1. The contributions are $50,$ 80, $60,$ 50, and $90. We need to find the mean and median of these contributions

STEP 2

First, we need to find the mean of the contributions. The mean is calculated by adding all the numbers and then dividing by the count of numbers.
$Mean = \frac{Sum\, of\, contributions}{Number\, of\, contributions}$

STEP 3

Now, plug in the given values for the contributions to calculate the sum.
$Sum\, of\, contributions = \$50 + \$80 + \$60 + \$50 + \$90$

STEP 4

Calculate the sum of the contributions.
$Sum\, of\, contributions = \$50 + \$80 + \$60 + \$50 + \$90 = \$330$

STEP 5

Now that we have the sum of the contributions, we can calculate the mean by dividing this sum by the number of contributions (5).
$Mean = \frac{\$330}{5}$

STEP 6

Calculate the mean of the contributions.
$Mean = \frac{\$330}{5} = \$66$

STEP 7

Next, we need to find the median of the contributions. The median is the middle number when the numbers are arranged in ascending order. If there is an even number of numbers, the median is the average of the two middle numbers.

STEP 8

Arrange the contributions in ascending order.
$\$50, \$50, \$60, \$80, \$90$

STEP 9

Since there is an odd number of contributions (5), the median is the middle number, which is the third number in the sorted list.
$Median = \$60$ Mike found that the mean contribution is $66 and the median contribution is$ 60.
