Hello students we are going to write here this is data about chattanooga residents.
00:06
So basically this is our table and we need to find mean yearly salary, standard aviation mode, median 70th percentile.
00:16
So let's start with our answering part.
00:18
We are going to extend this table to make it more clear.
00:22
This must be written something like this.
00:27
And if i write here, this must be written something like this.
00:38
And we are going to distribute this.
00:49
So if i write here, this is x minus x bar raise to power 2.
00:57
And we are going to write here for this.
01:02
First, we are going to calculate what would be our x bar value.
01:05
X bar value is mean, which is sum of data divided by number of data.
01:10
So sum of data is 49 plus 76 and this must be up to 94.
01:19
And if i write here for this, this must be divided by, this must be divided by if i write here.
01:32
So total data is 8 and sum value is 584 divided by, we are going to write here 8.
01:40
So basically this is 73...
