From the given table, we can deduce the following:
Relative frequency of undecided voters for each age group:
18 - 21 = 0.53
22 - 32 = 0.11
33 - 43 = 0.05
44 - 54 = 0.18
Over 55 = 0.13
Given that the government wants to concentrate on the largest number of undecided voters, the age group they should target is between 18 - 21.
They should target the age group between 18 - 21 because this age group has the highest relative frequency for undecided voters.
