Recall that costs are often reported by lot, rather than by individual units. Given the following lot costdata, calculate a unit theory learning curve equation. What is the slope? What is the theoretical first unit cost (T1)?

Lot No	Units	Cost ($k)
1	1-5	651.7
2	6-10	488.8
3	11-20	860.0
4	21-30	751.5
5	31-40	699.5
6	41-50	670.3
