The accounting department analyzes the variance of the weekly unit costs reported by two production departments. a sample of 16 cost reports for each of the two departments shows cost variances of 2.3 and 5.6, respectively. is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? use a = .10.
calculate the value of the test statistic (to 2 decimals).

Test Statistic is 2.34

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
