At a large business, employees must report to work at 7: 30 a. m. the arrival times of employees forms approximately a bell-curve distribution with mean 7: 22 a. m. and standard deviation 4 minutes. (a) use the 68-95-99.7 rule (also known as the empirical rule) to determine what percent of employees are late on a typical day. % (b) a psychological study determined that the typical worker needs four minutes to adjust to their surroundings before beginning their duties. use the 68-95-99.7 rule (also known as the empirical rule) to determine what percent of this business' employees arrive early enough to make this adjustment before the 7: 30 a. m. start time. %

Which are the best examples of costs that should be considered when creating a project budget?

Oerstman, inc. uses a standard costing system and develops its overhead rates from the current annual budget.the budget is based on an expected annual output of 120,000 units requiring 480,000 direct labor hours.(practical capacity is 500,000 hours)annual budgeted overhead costs total $772,800, of which $556,800 is fixed overhead.a total of 119,300 units, using 478,000 direct labor hours, were produced during the year.actual variable overhead costs for the year were $260,400 and actual fixed overhead costs were $555,450.required: 1. compute the fixed overhead spending variance and indicate if favorable or unfavorable.2. compute the fixed overhead volume variance and indicate if favorable or unfavorable.

Dr. sperry, a biologist, is using excel to track growth rates of different populations of bacteria. she has a very complex formula in one cell. it begins with “round”. dr. sperry would like to see exactly how excel’s calculation reached the final rounded value that she sees in the cell. what could dr. sperry do to best understand how the calculation was made? try different formulas on her own until she reaches the value shown in excel click on the evaluate formula button in the formulas tab and then click “step in” select the cell and then look at the formula in the formula field of the ribbon remove “round” from the formula in order to see the actual value before rounding
