In this question, we say that the table here is going to list the average annual costs and dollars of tuition and fees at public four -year colleges for selected years.
00:09
And we're going to answer parts a through c.
00:12
Now, only part a came through here, so i can only do part a because part b and c, the picture did not come through.
00:20
However, in part a, we're going to use a calculator to find the least squares regression line for these data where x equals zero corresponds to 1993, x equals two corresponds to 1995, and so on.
00:34
So we go to our calculators and we say, okay, i'm going to go to the stat followed by edit.
00:43
So go to the stat button followed by edit.
00:46
Anything that's in l1 and l2, we're going to clear out.
00:50
In l1, i'm going to put my x values.
00:52
So 1993 is year zero.
00:56
1995 is year two.
00:59
1997 is year four.
01:02
1999 is year six.
01:06
2001 is year eight.
01:09
Year 2003 is year 10.
01:12
And the year 2005 is the year 12...
