Old Professor Mullen Company uses flexible budgets. At normal capacity of 8,000 units, budgeted manufacturing overhead is: $32,000 variable and $90,000 fixed. If Old Professor Mullen had actual overhead costs of $125,000 for 9,000 units produced, what is the difference between actual and budgeted costs

Who is better at multi-tasking? in business, employees are often asked to perform a complex task when their atten-tion is divided (i.e., multi-tasking). human factors (may 2014) published a study designed to determine whether video game players are better than non–video game play-ers at multi-tasking. each in a sample of 60 college stu-dents was classified as a video game player or a non-player. participants entered a street crossing simulator and were asked to cross a busy street at an unsigned intersec-tion. the simulator was designed to have cars traveling at various high rates of speed in both directions. during the crossing, the students also performed a memory task as a distraction. two variables were measured for each student: (1) a street crossing performance score (measured out of 100 points) and (2) a memory task score (measured out of 20 points). the researchers found no differences in either the street crossing performance or memory task score of video game players and non-gamers. “these results,” say the researchers, “suggest that action video game players [and non-gamers] are equally susceptible to the costs of dividing attention in a complex task”

Russell's study compared gpa of those students who volunteered for academic study skills training and those who did not elect to take the training. he found that those who had the training also had higher gpa. with which validity threat should russell be most concerned?

In 2017, "a public university was awarded a federal reimbursement grant" of $18 million to carry out research. of this, $12 million was intended to cover direct costs and $6 million to cover overhead. in a particular year, the university incurred $4 million in allowable direct costs and received $3.4 million from the federal government. it expected to incur the remaining costs and collect the remaining balance in 2018. for 2017 it should recognize revenues from the grant of
