1.	If' a_(m) ' and' Deltaa_(m) are true value and mean absolute error respecively, then the magnitude of the quantity may lie between .......
Answer» `a_(m) + a_(N) "to" a_(m) - a_(n)` `a_(m) - Deltaa_(m) "to" a_(m) + Deltaa_(n)` `2a_(m) "to" Deltaa_(m)` `0 "to" 2a_(m)` SOLUTION :`a_(m) - Deltaa_(m) "to" a_(m) + Deltaa_(n)`
