Hello students, today we will discuss about this question.
00:04
In this question we are given that it is hypothesized that the human originated in east africa and migrated from there, we compute a measure of genetic diversity for the different populations and the geographic distance of each population from east africa as one would travel over the surface of the earth by land.
00:32
The relationship between these two variables that is shown in the figure below and data are given, that is genetic diversity.
00:42
Now here we need to describe the relationship between the genetic diversity and the distance from africa.
00:52
Thus these appears to be an association.
00:56
Or not.
00:57
So here we need to find does there appear to be an association or not.
01:12
If so it is positive or negative.
01:15
So positive or negative.
01:18
We need to find then strong or weak.
01:22
We need to find whether it is strong or weak is equal to question mark and linear or non -linear.
01:34
Linear or non -linear is equal to question mark and in the part b which of the following value gives the correlation between these two variable so here we need to find r is equals to question mark and here we are given options option a that is r is equals to minus 1 .22 option b that is r is equals to minus 0 .83 option c that is r is equals to minus 0 .14 option d that is r is equal to 0 .14.
02:08
Option e, that is, r is equal to 0 .83 and option f, that is the r is equals to 0 .122...
