Answer:

2.9106

Step-by-step explanation:

According to the information of the problem

Year 75   76   77   78    79    80    81      82 83 84 85 86 87

Lean 642 644 656  667   673  688 696  698 713 717 725 742 757

If you use a linear regressor calculator you find that approximately

y = 9.318 x - 61.123

so you just find x = 18  and then the predicted value would be 106mm

therefore the predicted value for the lean in 1918 was 2.9106
