Compute the leverage values for these data. (Round your answers to two decimal places.)
xi | yi | Leverage Values |
---|---|---|
4 | 12 | |
5 | 14 | |
7 | 16 | |
8 | 15 | |
10 | 18 | |
12 | 20 | |
12 | 25 | |
22 | 19 |
Do there appear to be any influential observations in these data? Explain.Minitab identifies an observation as having high leverage if
hi> 6/n; for these data, 6/n = .Since the leverage for the observation at
(xi,yi) =
is greater than 6/n
