4. Compare the lab test variance computed in requirement (1), a flexible-budget variance, with the sum of the variances in requirement (3-a). what is the relationship between the flexible budget variance and the total of the individual standard-cost variances? OThe flexible-budget variance equals the total of the individual standard-cost variances The flexible-budget variance is less than the total of the individual standard- cost variances. O The flexible-budget variance is greater than the sum of the total of the individual standard-cost variances
