These are the exercises for this week, from Larsen & Marx Chapter 11:
11.2.2: also, once you have drawn the line, evaluate if the straight line gives a good fit.
11.2.6
11.2.10
11.2.25: also, calculate the value of \(R^2\). For this you will need \(\sum_{i=1}^7\log{y_i^2} = 18.91127\), and also \(\sum_{i=1}^n(x_i - \bar{x})(y_i-\bar{y}) = \sum_{i=1}^nx_i y_i - n\bar{x}\bar{y}\).
(I was half-tempted to give you 11.2.24, but part (a) should be easy, and part (b) is difficult because you might not even know what graph paper is nowadays)
If there is anything that you particularly want feedback on, please ask. We will try to help.
