EX 10-28 (Algo) Cost Variance Investigation (LO 10-4) The director of cost management for Odessa Company uses a statistical control chart to help management determine when to investigate variances. The critical value is 1 standard deviation. The company incurred the following direct-labor efficiency variances during the first six months of the current year. The standard direct-labor cost during each of these months was $32,000. The controller has estimated that the firm's monthlv thumb is to investigate all variances equal to or greater than 5 percent of standard cost. 2-b. Based on the cutoff value, which month will have its direct-labor efficiency variance investigated? Complete this questior below. Determine the cutoff valur thumb is to investigate all standard cost. umb is to investigate all variances equal or greater than 5 percent of standard st. b.
