Help with figuring out an average age of people listed in a digital file?

2015-09-10T09:54:22Z

The ages of 10 persons are stored using 7 bits each in a digital file. The contents of the digital file are: 1011001011-
1100110100-
1000010001-
0100110110-
1011100001-
0101011101-
1111000110

Decode the digital file and calculate the average age in this group of people. Any assistance would be appreciated, thank you in advance!

convert to decimal, add them together, then divide by the number of entries.
