Answer:
The option that is not true about variance investigation is A) every variance is investigated.
Step-by-step explanation:
Every business projection and forecast is made based on speculation. These estimates in theory vary with what is obtainable in practice. Therefore, variance is inevitable.
It is not every variance that is investigated. Variances are not investigated unless they are large enough to be of concern and the investigation should be undertaken only if the anticipated benefits are greater than the expected costs.
Variance investigation models are concerned with decisions to investigate the cause of particular variances and in particular, to distinguish significant deviations from random fluctuations.
