You are a commercial shipyard analyst, working for a manufacturing company, examining a relatively new program. A recent program review has provided the following values:

Lot	Units in Lot	Expected lot cost	Actual lot cost
1	2	512	562
2	12	2350	2672
3	17	3179	3691
4	32	5036	5363

Theres no question that actual costs have exceeded planned costs, however, your production supervisor is interested in whether this review provides evidence of a fundamental change to the anticipated production learning that was supposed to take place for this system. Answer the questions below considering costs from the company's desired position.

a) Determine whether or not there has been a change to the learning anticipated for this program. Support your claim with specific calculations based on the data above.

b) What would you anticipate the actual cost to be for a proposed fifth lot of 50 units?
