Solution

1. Break Down the Problem

To find the median, we first need to organize the given data in ascending order. The median is the middle number in a sorted list.

2. Relevant Concepts

The median can be computed as follows:

  • If the number of observations (n) is odd, the median is the middle number, which can be found at the position (n+1)/2(n + 1)/2.
  • If n is even, the median is the average of the two middle numbers, located at positions n/2n/2 and (n/2)+1(n/2) + 1.

3. Analysis and Detail

  1. Sort the data: The data provided is: 80,999,4331,951,7290,7629,456,7391 80, 999, 4331, 951, 7290, 7629, 456, 7391 Sorting these values: 80,456,951,999,4331,7290,7391,7629 80, 456, 951, 999, 4331, 7290, 7391, 7629

  2. Count the number of observations: There are 8 observations, which is even.

  3. Determine the positions for the median: The two middle numbers are at positions 44 and 55:

    • 4th number: 999
    • 5th number: 4331
  4. Calculate the median: Median=999+43312=53302=2665 \text{Median} = \frac{999 + 4331}{2} = \frac{5330}{2} = 2665

4. Verify and Summarize

We calculated the median based on the sorted data and confirmed we have 8 values, which leads to an average of the middle two numbers.

Final Answer

The median is 2665.00 2665.00 .
