Fall City Hospital has an outpatient clinic. Jeffrey Harper, the hospital$$s chief administrator, is very concerned about cost control and has asked that performance reports be prepared that compare budgeted and actual amounts for medical assistants, clinic supplies, and lab tests. Past financial studies have shown that the cost of clinic supplies used is driven by the number of medical assistant labor hours worked, whereas lab tests are highly correlated with the number of patients served.

The following information is available for June:

Medical assistants Fall City$$s standard wage rate is $$18$ per hour, and each assistant is expected to spend $24$ minutes with a patient. Assistants totaled $840$ hours in helping the $1,670$ patients seen, at an average pay rate of $$17\mathrm{.}50$ per hour.

Clinic supplies The cost of clinic supplies used is budgeted at $$15$ per labor hour, and the actual cost of supplies used was $$9,650.$

Lab tests Each patient is anticipated to have three lab tests, at an average budgeted cost of $$67$ per test. Actual lab tests for June cost $$347,193$ and averaged $3\mathrm{.}3$ per patient.

Required:

$1.$ Prepare a report that shows budgeted and actual costs for the $1,670$ patients served during June. Compute the differences $($variances$)$ between these amounts and label them as favorable or unfavorable.

$2.$ On the basis of your answer to requirement $(1),$ determine whether Fall City has any significant problems with respect to clinic supplies and lab tests.

$3-$a$.$ Determine the spending and efficiency variances for lab tests. $($Hint: In applying the overhead variance formulas, think of the number of tests as the activity level, and think of the cost per test as analogous to the variable overhead rate.$)$

$3-$b$.$ Does it appear that Fall City has any significant problems with the cost of its lab tests?

$4.$ 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?
