Answer: Company A mean = 14.65 million Company B mean = 14.32 million.

Step-by-step explanation:

The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores.

Company A mean = 12.8 + 15.0 + 31.0 + 13.0 + 14.0 + 12.9 + 12.7 + 11.9 + 11.7 + 11.5 = 146.5/ 10 = 14.65 million

Company B mean = 13.8 + 14.0 + 14.5 + 14.3 + 14.6 + 14.5 + 14.2 + 14.7 + 14.4 + 14.2 = 143.2/ 10 = 14.32 million

The median is the middle score of a distribution. To calculate the median

Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Currently i'm providing you the mean solution im working on the median I haven't learned it.

Answer:

  • Part A. Mean 14.65 and 14.32
  • Part B. Median 12.85 and 14.35
  • Part C. Company B

Step-by-step explanation:

Company A

Sum:

  • 12.8 + 15.0 + 31.0 + 13.0 + 14.0 + 12.9 + 12.7 + 11.9 + 11.7 + 11.5 = 146.5

Mean:

  • 146.5/ 10 = 14.65

Numbers in ascending order:

  • 11.5, 11.7, 11.9, 12.7, 12.8, 12.9, 13, 14, 15, 31

Median:

  • (12.8 + 12.9)/2 = 12.85

Company B

Sum:

  • 13.8 + 14.0 + 14.5 + 14.3 + 14.6 + 14.5 + 14.2 + 14.7 + 14.4 + 14.2 = 143.2

Mean:

  • 143.2/ 10 = 14.32

Numbers in ascending order:

  • 13.8, 14, 14.2, 14.2, 14.3, 14.4, 14.5, 14.5, 14.6, 14.7

Median:

  • (14.3 + 14.4)/2 = 14.35

Company B has a greater median which indicates more stable and consistent performance. It have very close mean and median, which tells us about stability.

Company A has greater difference between mean and median, which indicates inconsistent performance. Having a greater mean doesn't confirm a better performance.
