## Main Question or Discussion Point

Ok. I'm fairly new so go easy on me. I apologise if this is posted in the wrong section.

Can someone point me in the right direction of being able to work out samples of a web poll. A web poll I did returned the following results for a sample of 40 people and spending habits of a particular item.

What I'd like to be able to figure out is:

(1) what would be the average; and

(2) How accurate my sample size is (eg., We can be 99% sure that the average is x with a +/- 5% error margin) <-- I hope that makes sense.

Can someone point me in the right direction of being able to work out samples of a web poll. A web poll I did returned the following results for a sample of 40 people and spending habits of a particular item.

Code:

```
Range Poll %
$0 - $500 6 15.00%
$501 - $800 6 15.00%
$801 - $1000 6 15.00%
$1001 - $1200 3 7.50%
$1201 - $1500 2 5.00%
$1501 - $2000 5 12.50%
$2001 - $3000 7 17.50%
$3001+ 5 12.50%
```

(1) what would be the average; and

(2) How accurate my sample size is (eg., We can be 99% sure that the average is x with a +/- 5% error margin) <-- I hope that makes sense.
