The standard ratio of direct-labor hours to machine hours is 4:1. The standard direct-labor rate is $15.08. *Source of data: Alan S. Levitan and Sidney J. Baxendale, "Analyzing the Labor Efficiency Variance to Signal Process Engineering Problems," Journal of Cost Management 6, number 2, page 70. PR 10-38 (Static) Part 1: Calculate the following amounts. Required: 1-a. Which of the following amounts were used to calculate January's standard direct-labor hours? 1-b. Which of the following amounts were used to calculate January's direct-labor efficiency variance? 2. Calculate the following amounts. a. The standard direct-labor cost for each of the 10 months. b. For each month, 20 percent of the standard direct-labor cost. 3. Suppose management investigates all variances in excess of 20 percent of standard cost. Which months contain a variance that would be investigated? Calculate the standard direct-labor cost and 20 percent of the standard direct-labor cost for each of the 10 months. Suppose management investigates all variances in excess of 20 percent of standard cost. Which months contain a variance that would be investigated? Note: Select "Yes" if the listed month contains variance that would be investigated, and "No" if it is not. Round your final answers to the nearest whole dollar amount
