Answer: 0.67
Explanation:
From the question, we are informed that Levine Inc. is considering an investment that has an expected return of 15% and a standard deviation of 10%.
The investment's coefficient of variation will be the standard deviation divided by the expected return. This will be:
= 10/15
= 0.67

Explanation:
1. The ceterus paribus effect gives us to what extent, the effect of a variable has on another variable, while holding all other factors fixed. Analysing job training of workers on productivity will give us results that are not biased since we will not be taking account of other factor variables in the calculations. When 2 firms are the same in almost every aspect apart from number of hours on training, then we will find out that each firm would have different levels of workers output. So we should know if workers output increases due to job training.
2. When it comes to provision of training, furms do these based on characteristics of the workers. Some of these characteristics are measurable while some are immeasurable
Measurable:
Experience on the job,
Productivity
Level of education,
immeasurable :
Skill set
Vision
Likeliness to bstay at firm
3. Apart from worker characteristics, productivity also depends on other factors one of which is technological change. A technological change can bring about increased efficiency and greater output by the worker. Different firms using different capital and technological combination are quite likely to have different output levels.
4. A positive correlation between job training and productivity cannot be used to ascertain if job training makes worker more efficient this is due to the fact that correlation only tells us if variables are in coexistence. So a positive correlation does not tell us that job training is indeed bringing about changes in the productivity of workers.
