Mr. Fleming asked you to evaluate costs in the hospital's lab for the past month. The following information is available: a. Two types of tests are performed in the lab-blood tests and smears. During the past month, 1,800 blood tests and 2,400 smears were performed in the lab. b. Small glass plates are used in both types of tests. During the past month, the hospital purchased 12,000 plates at a cost of $56,400. 1,500 of these plates were unused at the end of the month; no plates were on hand at the beginning of the month. c. During the past month, 1,150 hours of labor time were recorded in the lab at a cost of $21,850. d. The lab's variable overhead cost last month totaled $7,820. Valley View Hospital never used standard costs. By searching industry literature, however, you determined the following nationwide averages for hospital labs: Plates: Two plates are required per lab test. These plates cost $5.00 each and are disposed of after the test is completed. Labor: Each blood test should require 0.3 hours to complete, and each smear should require 0.15 hours to complete. The average cost of this lab time is $20 per hour. Overhead: Overhead cost is based on direct labor-hours. The average rate for variable overhead is $6 per hour. Required: W 1. Compute a materials price variance for the plates purchased last month and a materials quantity variance for the plates used last month. 2. For labor cost in the lab: a. Compute a labor rate variance and a labor efficiency variance. b. In most hospitals, one-half of the workers in the lab are senior technicians and one-half are assistants. In an effort to reduce costs, Valley View Hospital employs only one-fourth senior technicians and three- fourths assistants. Would you recommend this policy be continued? Explain. 3. Compute the variable overhead rate and efficiency variances. Is there any relation between the variable Mr. Fleming asked you to evaluate costs in the hospital's lab for the past month.
