EJB Company used a "normal" production level of 10,000 units to determine the standard per-unit cost of manufacturing overhead. Which of the following statements is not true? Multiple Choice O There is no overhead volume variance for a given month if actual production that month is 10,000 units. When actual production exceeds 10,000 units, use of standard costs results in a favorable overhead volume variance. Overhead variances arising as a result of producing more or less than 10,000 units do not indicate either strong or poor performance by the Production Department. When actual production is less than 10,000 units, use of standard costs results in an unfavorable total overhead variance
