The following is a solution number seven. And this gives you a data set. There are 12345678 data values. And were asked to make a scatter plot, er scattered diagram. And then we're going to say whether it's deterministic or random and then we're going to say if it appears to be linear And you can just plot these points like you would on a Cartesian plane. But I always feel like if you have technology you might as well use it. So I'm gonna use the T. I-84 graphing calculator. And if you go to stat and then edit, you can see I put the X values in L. One and then the Y values in L. Two. And then if you go to second Y equals and just make sure that first step plot is on and uh it's just going to it and say it's it's on. And then for the type, choose this first one is the scatter plot. The X list is L. One the wireless dezell too, unless you put it in a different column. And then as for Mark you can choose any of these four. I think the first one's easiest to see though. And then whenever you press graph you should be able to see those data values. Now if you don't see those data values that's fine. You can just zoom in your windows a little bit off which is okay if you just go to zoom and then this ninth option here zoom stat that should give you a pretty clear picture. So this is what your scatter plot should look like. This is you know a computer output but you can do that manually and just make your yourself a Cartesian plane. But these are all the 10. Um Or actually I think there are eight data values there. So that's part A and part B. Is it deterministic or random? So uh this one, it's gonna be random because it doesn't follow an exact straight line and there is no exact pattern. In fact, if we found The correlation coefficient, it wouldn't be exactly one, it would actually be .8 or nine or something. But um that way we know it's gonna be random. So let's go and write that down. There's a randomness element to it element. Yeah, because the points do not form a perfect line. Okay, the x value does not 100% predict the y value, so there is a randomness to it, and then it asks us is this linear? And it does seem linear. There's a linear relationship. So it seems there is a linear relationship, and you can just determine that just by going back to that scatter plot, it kind of looks like this is a, you know, a nice straight line, there's very little deviation, it's not, you know, a circle or it's not going up and down, it's pretty much just going up from left to right, so this one appears to be linear.
