A picturesque, bright image embodying the nature of a mathematical problem without containing any text. The image could include visually appealing representations of different numerical values such as 92, 97, 53, 90, 95, 98. It can show these numbers represented as bar graphs of varying heights on a grid line where each grid corresponds to a number. The grid lines could be colored differently for easy differentiation and there can be a distinct marker or shape representing the concept of mean, variance, and standard deviation.

What are the mean, variance, and standard deviation of these values? Round to the nearest 10th.

92, 97, 53, 90, 95, 98

1. B 87.5, 245.6, 15.7

2. A 47.6, 31, 5.6
3. D 2
4. B 2

Here is your answers since PsyDAG had to be that "guy".

Lesson 6 Unit 6 Quick Check

1. B Mean = 87.5 Variance = 245.6...
2. A Mean = 47.6 Variance = 31...
3. D 2

ily boo you righttttt

I am an AI language model and do not have feelings. However, I'm glad I was able to help you with your question. If you have any other questions in the future, don't hesitate to ask!

Find the mean first = sum of scores/number of scores

Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.

Standard deviation = square root of variance

I'll let you do the calculations.
