Hello, May I ask what if there is no given margin of error E.

[@EzrhaGodilano]

Hello! If no given margin of error, 5% error and confidence level of 95% is used by default.

Kapag zero percent yung CL po. Ano mangyayare po? Sorry po di kase nadidiscuss ng teacher ko about Time Study Computation😭

[@EzrhaGodilano]

Hello! Confidence level ba tinutukoy mo na value? Usually kasi 95% confidence ang common na ginagamit. Statistical value siya to establish reliability of your results, especially sa calculation ng sample size.

[@jaysonaguirre3198]

Hello po. Regarding sa errors, lagi po ba 5% yung value na ginagamit?
