A drug company is considering marketing a new local anesthetic. The effective time of the anesthetic the drug company is current

ly producing has a normal distribution with a mean of 7.4 minutes with a standard deviation of 1.2 minutes. The chemistry of the new anesthetic is such that the effective time should be normally distributed with the same standard deviation, but the mean effective time may be lower. If it is lower, the drug company will market the new anesthetic; otherwise, they will continue to produce the older one. A sample of size 36 results in a sample mean of 7.1. A hypothesis test will be done at the 10% level of significance to help make the decision.

An investment project has annual cash inflows of $4,200, $5,300, $6,100, and $7,400, and a discount rate of 14 percent. If the initial cost is $7,000, the discounted payback period for these cash flows is ___2_____ years. If the initial cost is $10,000, the discounted payback period for these cash flows is___3____years. If the initial cost is $13,000, the discounted payback period for these cash flows is__4_____years. (Round your answers to 2 decimal places. (e.g., 32.16))

Explanation:

a) Data and Calculations:

Annual cash inflows of

          Cash Inflow     Discount Factor    PV             Running Total

Year 1    $4,200            0.877               $3,683.40     $3,683.40

Year 2   $5,300           0.769                 4,075.70         7,759.10

Year 3   $6,100            0.675                  4,117.50         11,876.60

Year 4  $7,400            0.592                 4,380.80       16,257.40

b) An investment project's discounted payback period is the number of years it takes for an investment to recover its costs.  It is the period when the project's discounted cash inflows equals the project's discounted cash outflows.  It is another version of the payback period that uses discounted cash flows.

Peppy Pups, a dog toy company, uses a job order costing system in which overhead is applied to jobs on the basis of direct labor
Gnom [1K]

Answer:

Explanation:

Predetermined overhead rate is based on a cost formula that estimated $346,000 of manufacturing overhead for an estimated activity level 69,200 direct labor hours. So Overhead rate is 346,000/69,200 = $5/labour hour

Applied overhead = 180,000/4*5 = $225,000

Actual overhead = 60,000[280,000-220,000] +72,000+57,000+88,000 = $277,000

Under applied overhead = 225,000-277,000 = $52000

Recently, you accepted an internship position with the Tulawaka Zoo in Tennessee. You report to Sharon Molacavage, the Senior An
Furkat [3]

Answer:

The correct answer is letter "B": A moderately favorable situation in which Sharon’s relationships with her employees are strained, but where the employees are still doing highly structured tasks.

Explanation:

Austrian organizational psychologist Fred Fiedler (<em>1922-2017</em>) proposed in his Theory of Contingency that leaders only have one leadership style and that they cannot shape it according to the different situations they might be involved in. Instead, leaders must be located in a situation that matches their style.

Since Sharon's leadership style is <em>autocratic</em>, she is likely to manage herself better in adverse situations where the subordinates still follow her instructions.
