The actual direct labor hours used for the output produced in March are also provided:

Required:

1.Compute the direct labor mix and yield variances. (Round standard price of yield to four significant digits.)

2. Compute the total direct labor ef

ciency variance. Show that the total direct labor efficiency variance is equal to the sum of the direct labor mix and yield variances.
