The numbers are not clustered around a common number. Two of the numbers are very large and one is very small.
The reasoning that the given numbers 7.95, 8.11, 78.5, 8.05, 79.4, and 0.815 begin with a 7 or 8 can be estimated using cluster estimation is not accurate because the given numbers are not closer to any one number.
Given :
7.95 + 8.11 + 78.5 + 8.05 + 79.4 + 0.815
To estimate sums and products of the given numbers when the numbers are cluster near or is close in value to a single number, Cluster Estimation is use.
The given numbers 7.95, 8.11, 78.5, 8.05, 79.4, and 0.815 are not add up by suing the cluster estimation because these numbers are not closer to any one number.
Therefore, the reasoning that the given numbers 7.95, 8.11, 78.5, 8.05, 79.4, and 0.815 begin with a 7 or 8 can be estimated using cluster estimation is not accurate.
