The range of values likely to contain the true value of the population parameter is from 43% to 49%.

This is referred to a statistical measurement for a particular population and is usually fixed.

We were told that the margin of error is 3 percentage points. This therefore means:

(46 ± 3) % = (46-3)% to (46+3)%

Therefore the range of values is 43% to 49%.
