To get the best deal on a CD player, Tom called eight appliance stores and asked the cost of a specific model. The prices he was quoted are listed below: $298 $125 $411 $157 $231 $213 $304 $272

$84.86

Explanation:

I'm guessing they want you to find the standard deviation.

It would be easy to do this in a statistical calculator, but I suspect they want you to do it by hand.

Here are the steps for a manual calculation.

1. Count the elements in the data set

N = 8

2 Calculate the sum of the data set

3. Calculate the mean

4. Calculate the standard deviation

(a) Subtract the mean from each data point

(b) Square the differences

(c) Add the squares  of the differences

(d) Divide the sum by the number of terms

(e)Take the square root of the result

We can set up a table to organize the calculations.

the effect is that geography has alot to do with how level the ground is and how structurally safe it is. it can also show like cracks in the ground and if mountains are safe to be by. hope this

it was decent, could have been a little better.. how bout you lol.
