Okay, we're going to do question 51 of chapter 15.
00:05
Part a, we're going to regress with excel, and then this is the result that we got for coefficients.
00:14
So from these coefficients, we can find the regression equation, where y is by again, and x1 is treated where.
00:27
So this is the anova result, and we're going to use significance of this entry.
00:33
And since the significance of is less than alpha, we determine that relationship is significant.
00:47
And to conclude whether the fit is good or not, we have the, we have to look at the regression statistics that is given by the excel.
00:58
So we're going to look at the adjusted square here, and we see that this is 0 .89.
01:05
So the model is a good fit...
