Write a table to show your steps for calculating the standard deviation and then use your table to calculate the standard deviation of the values listed: 10, 11, 12, 10.5, 11.25, 12.25, 10

Step-by-step explanation:

The Standard Deviation is defined as

Where is the standard deviation, is the mean and is the total number of data.

So, first, we need to find the mean of the data set.

Now, we have to subtract each data with the mean to then elevate the differnece to the square power.

Then, we sum all these results.

Next, we divide the sum by

Finally, we apply the square root.

Therefore, the standard deviation for the given data set is 1.65.

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.
