Answer:
A. Observational study
Explanation:
An observational study measures the characteristics of a population by studying individuals in a sample, but does not attempt to manipulate or influence the variables of interest.
A designed experiment applies a treatment to individuals (referred to as experimental units or subjects) and attempts to isolate the effects of the treatment on a response variable.
Hence, we can see that proposed study is observational.
Practicia completes the job in one hour = 1/4
Naoimi completes the job in one hour = 1/5
If Parcticia and Naoimi does it together,let us suppose in x number of hours.
The equation so form is:
(1/4)*x + (1/6)*x = 1 (i.e job finished)
The Least common multiple(LCM) of 4 and 6 = 12
12*(1/4)*x + 12*(1/6)*x = 12*1
Therefore, solving the equation we get,
3x + 2x = 12
5x = 12
x = 12/5
x= 2 2/5 hours or 2.24 hours
Therefore number of hours they took to complete the work is 2 hours and 24 minutes or 2.24 hours.
Answer:
The answer is D. Counting inventory on hand and comparing counts to the perpetual inventory records
Explanation:
Corrective controls are designed to correct errors or irregularities that have been detected and this can only be achieved if comparison of counts are made be going through the records another time.
