Answer: 6.
Step-by-step explanation: To find the mean, the first step is to add all the data together. Here's how it should look:
2 + 3 + 6 + 6 + 7 + 8 + 8 + 8 = 48.
Next, you need to divide whatever you get after adding the data by how many numbers there are for your data. In this case, 48 was the answer when we added all the data. In total, you have 8 numbers in your data, so you need to divide 8 from 48. It should look like this:
48 / 8 = 6.
Therefore, the mean for this data set is 6.
Have a great day! :)

Using compound interest, the rates per compounding period are given as follows:
a) 0.1273 = 12.73%.
b) 0.0833 = 8.33%
c) 0.0617 = 6.17%
<h3>What is compound interest?</h3>
The amount of money earned, in compound interest, after t years, is given by:

In which:
- A(t) is the amount of money after t years.
- P is the principal(the initial sum of money).
- r is the interest rate(as a decimal value).
- n is the number of times that interest is compounded per year.
The <u>interest rate per compounding period</u> is given as follows:

For item a, the parameters are:
r = 0.12, n = 52.
Hence:

For item b, the parameters are:
r = 0.08, n = 104.
Hence:

For item c, the parameters are:
r = 0.06, n = 12.
Hence:
