Unformatted text preview: 1 11. (a) Scatter plot.: Figure 2: Scatterplot Caliper 1 vs Caliper 2 (b) Pearsons correlation coecient=0.985 (c) Spearmans correlation coecient=0.982 12. (a) Y=194+0.934X (b) Y=194+0.934*300=474.2. (c) Average sediment conductivity increases by 0.934*50=46.7. 13. (a) Y=2.18+0.66X (b) Let Y = 12 Y and X = 12 X , Y = 12 Y = 12 * (2 . 18) + 0 . 66(12 X ) = 12 * (2 . 18) + 0 . 66 X Thus the intercept is 12*(2.18) and the slope is 0.66. The intercept increases by a factor of 12 and the slope remains the same. (c) Y=2.18=0.66*14=7.06. (d) Average distance increases by 4*slope=4*0.66=2.64. 2...
