Hi, i'm david and i'm here to help you and see your question.
00:03
Now let me bring up your question here.
00:07
In the question here, we are going to discuss about the linear discussion.
00:12
Here we will revise you about the linear discussion of the form white heart equal to the p0 plus the p1 times the x.
00:22
Now in this question here we want to predict the sim stolic blood pressure using the left arm and then we will see that we will have the data of the right arm and the data on the left arm and then we want to find the best predicted symptom of the pleasure in the left arm given the symptom of the blood pressure on the right arm it means that we have the y that will be the left arm and the x will be the right arm pleasure and here with the dataset we can pass the data into the calculator to find the value of the b0 and the p1 so if we compute we have the y heart it will equal to now we will have here this one will be the right am it will be the x and the left end will be the y therefore we will have this one will be the the volume of the 100 girls with the 175 and then 99 girls with the 170 and 93 girls with the 146 79 girls with the 147 80 girls with the 147 and then we have white heart it will equal to the 52 so this one will be the 52 pound 9, 2, 3, i round you the 3 decimal places.
02:11
And then we have the p1, it will equal 2, plus 1 .1530, i round to the 3 decimal places will be the 5 4 time with the x.
02:26
And this will be the linear question we are looking for for the first question a.
02:33
And then also we will need to find the correlation coefficient r.
02:39
And then we get this one will equal to the 0 .a196 and we need to make sure this all here will be significant.
02:49
To make sure any significant i will bring up the table of the critical value for this one...
