In Data Set B we have details regarding insurance claims over a defined period (eg 2007 - 2009) for the same insurance company.

I would like to check if the following calculations would make sense.

Data Set A has been sorted via customer segments. Hence we can say that customers in the (mature professional age 25-30) accounted for 25% of the customer base for the insurance company.

Data set B has also been sorted via customer segments. Here we find that customers in the (mature professsional age 25-30) accounted for 10% of the claims.

Would it make sense to then conclude that the expected number of claims from the mature professional segment would be ( 10%*25%) = 2.5%

cheers
