Hello Sir,
Hope you are keeping well!
I have 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 minutes
Based upon the above data, the rate of learning was closest to?
My question : as per answer it is 85% but I am not really sure how.. As per my understanding we should be doing like this :
Units Total time taken Average time
1 100 100
2 70 100*r
4 57 100*r2
so,
57=4*100*r2
r=38%
Please correct me .October 27, 2020 at 3:14 pm #593269The average time per batch if they make 4 batches is (100 + 70 + 62 + 57) / 4 = 72.25 minutes
Therefore 100 x r^2 = 72.25
r^2 = 0.7225
r = square root of 72.25 = 0.85 or 85%
I do suggest that you watch my free lectures on this.
