Hi,
Could u pls advise me tge answer for the below question:
The times taken to produce each of the first four batches of a new product were as follows:
Batch number Time taken
1 100 minutes
2 70 minutes
3 62 minutes
4 57 minutesBased on the above data, the rate of learning was closest to
A. 70%
B. 72.25%
C. 82%
D. 85%From my calculation, the answer I get is 75%
y = ax’2
0.95 = 1.67 x 4’b
Thank you
Why are you attempting questions for which you do not have an answer? You should be attempting questions using a Revision Kit from one of the ACCA approved publishers.
The average time per batch when they produce 4 batches is (100+70+62+57)/4 = 72.25 minutes.
Making 4 batches involves doubling twice.
Therefore the learning rate = square root of (72.25/100) = 0.85 (or 85%).
I do suggest that you watch my free lectures on learning curves. The lectures are a complete free course for Paper PM and cover everything needed to be able to pass the exam well.
