Hey there, welcome to numerate.
00:03
We are asked to choose the following statement that holds true for this data set here.
00:11
So let us rewrite this data set first from least to greatest.
00:16
So we're going to start with the value 4, 5, 6, 7, 7, and 12.
00:33
So this is what we did.
00:36
Organize it from least to greatest.
00:41
As you can see, smallest to largest.
00:50
So the reason why we organize it from least to greatest first is because we can see the center better, the middle value better.
01:00
So with this, we can start by finding our mean.
01:07
So our mean here will equal the sum of all the values above.
01:15
So we add up all the values.
01:16
And divide by our sample size 7.
01:21
So actually let me see this.
01:25
812, so i'm missing one data value, that's why we're missing the 8 and then 12.
01:37
Alright, so we add up all the values, giving us a sum of 49, and 49 divided by 7, we know that would be 7.
01:46
So our mean is 7...
