Hi, i'm david and i'm here to have you answer your question.
00:04
Now let me bring up your question here.
00:07
In this question we are given the three parts.
00:11
In the first part we will discuss about the technique to use to predict the value of one variable on the basis on the variables.
00:21
Now in a to predict we need to use the linear regression because we will find the formula relating the x and the y.
00:33
Therefore the answer for the 1 the past 1 will should use will be the regression analysis so the answer for the part 1 will be the d now for the 2 we are given the equation regression line then y heart equal to the 3 minus 2 x now for the when x equal to 2 minus 1 we can try y heart equal to the 3 minus 2 times minus 1 so equal to 5, it's not equal to 1.
01:06
Therefore it's not the a.
01:08
For the b, y heart equal to the 3 minus 2 times 1, and equal to 3 minus 2 equal to 1.
01:16
And it's not equal to the 2, therefore not b...
