Required information The Chapter 10 Form worksheet is to be used to create your own worksheet version of the main example in the text. Requirement 2: Revise the data in your worksheet to reflect the results for the subsequent period as shown below: a-1. What is the materials quantity variance? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance)). a-2. What is the materials price variance? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance)). b-1. What is the labor efficiency variance? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorabl and "None" for no effect (i.e., zero variance)). b-2. What is the labor rate variance? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Round your final answer to nearest whole dollar amount) 1. What is the variable overhead efficiency variance? (Indicate the effect of each variance by selecting "F" for favorable, "U" for nfavorable, and "None" for no effect (i.e., zero variance)). c-2. What is the variable overhead rate variance? (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance))
