Answer:
a. 41.6 million
b. 42.28 million
Explanation:
A) GIven
forecast in june = Sjune = 42 million
Checks recived in june = Xjune = 40 million
Smoothing constant = a = 0.2
So for july
Sjuly = a*Xjune + (1-a)*Sjune
=0.2*40 + (1-0.2)*42 million
=8+33.6 = 41.6 million
B) forecast in july = Sjuly = 41.6 million
Checks recived in july = Xjuly = 45 million
Smoothing constant = a = 0.2
So for August
Saugust = a*Xjuly + (1-a)*Sjuly
=0.2*45 + (1-0.2)*41.6 million
=9+33.28 = 42.28 million
<em>Note: This uses an exponential smoothing to forecast the results, but from the number of checks recived we see that it increases linearly. So we need a linear forecasting method .</em>
Answer: A. True
Explanation: If he were inexperienced in this field or he was doing it as his hobby (casual objectives) with no goal to reproduce or add to the data already published, or were there people involved in his research, then this would have been categorized as informal research. However this setting is strictly formal, and authenticity of data is mandatory. Print and online journal articles contain the case studies already researched thoroughly.
Answer:
The correct answer is letter "A": Screening mechanism.
Explanation:
The screening mechanism is the activity in which people identify good qualities in others by evaluating their actions and matching them with their own behavior so they can eventually qualify those other people as suitable for them or not.
In the example, <em>Sally must consider a good practice to give generous tips to waiters since only if Andy, her date, does such a thing, she will consider dating him again. What Sally conducted is an example of a screening mechanism.</em>
