Founders State Bank developed a standard for teller staffing that provided for one teller to handle 13 customers per hour. During June, the bank averaged 52 customers per hour and had five tellers on duty at all times. (Relief tellers filled in during lunch and rest breaks.) The teller compensation cost is $13 per hour. The bank is open eight hours a day, and there were 20 working days during Required: a. Calculate the teller efficiency variance during June expressed in terms of number of tellers and cost per hour. b. Now assume that in June, during the 11 A.M. to 1 P.M. period every day, the bank served an average of 78 customers per hour. During the other six hours of the day, an average of 39 customers per hour were served. 1. Calculate a teller efficiency variance for the 11 to 1 period expressed in terms of number of the for her month. 2. Calculate a teller efficiency variance for the other six hours of the day expressed in terms of number of tellers per hour and total cost for the month. Calculate the teller efficiency variance during June expressed in terms of number of tellers and cost per hour. (Do not round intermediate calculations. Round "Tellers per hour" to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Now assume that in June, during the 11 A.M. to 1 P.M. period every day, the bank served an average of 78 customers per hour. During the other six hours of the day, an average of 39 customers per hour were served. Calculate a teller efficiency variance for the 11 to 1 period expressed in terms of number of tellers per hour and total cost for the month. (Do not round intermediate calculations. Round "Tellers per hour" to 2 decimal places. Indicate the effect of each variance by selecting " F " for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).) Now assume that in June, during the 11 A.M. to 1 P.M. period every day, the bank served an average of 78 customers per hour. During the other six hours of the day, an average of 39 customers per hour were served. Calculate a teller efficiency variance for the other six hours of the day expressed in terms of number of tellers per hour and total cost for the month. (D not round intermediate calculations. Round "Tellers per hour" to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance).)
