Find the mean of the data

Mathematics

Triss [41]2 years ago

<h3>Answer:  6.282</h3>

Explanation:

Refer to the table below. I've added a third row where I multiplied each x value with its corresponding frequency value f. We can refer to this row as the xf row.

Once we know the xf values, we add them up to get 245.

We'll then divide that result over the sum of the frequency values (add everything in the second row). The sum of the frequency values is 39.

So the mean is approximately: 245/39 = 6.282051 which rounds to 6.282

Notice that this mean value is fairly close to the x value which has the highest frequency.

evablogger [386]
I could be wrong because people do make mistakes, but i’m pretty sure the answer i got was right
$128.60
explanation:
$257.20 divided by 4=$64.30
$257.20-$64.30=$192.90
$192.90 divided by 3=$64.30
$192.90-$64.30=$128.60
therefore, she has $128.60 left from her paycheck after bills
