Answer:
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Explanation:
To calculate the standard deviation of the investment, we must first calculate the expected or mean return of the investment. The expected or mean return can be calculated as follows,
r = pA * rA + pB * rB + ... + pN * rN
Where,
- pA, pB, ... represents the probability of state occurrence
- rA, rB, ... represents return A, return B and so on under each state
r = 0.2 * 0.16 + 0.4 * 0.12 + 0.2 * 0.05 + 0.2 * -0.05
r = 0.08 or 8%
The formula to calculate the standard deviation of a stock/investment is as follows,
SD = √pA * (rA - r)² + pB * (rB - r)² + ... + pN * (rN - r)²
SD = √0.2 * (0.16 - 0.08)² + 0.4 * (0.12 - 0.08)² + 0.2 * (0.05 - 0.08)² + 0.2 * (-0.05 - 0.08)²
SD = 0.0740270 or 7.40270 percent rounded off to 7.403 percent
Answer:
E. separation, self-service, automation, and scheduling.
Explanation:
Increase in productivity in a business aims to increase the efficiency of an individual or process involved in production of useful output.
Strategies for improving productivity includes separation, self-service, automation, and scheduling.
When there is seperation in services available to a customer, they easily identify the most relevant one to them.
Self service gives control of the process to the customer, resulting in greater satisfaction.
Automation reduces the turnaround time of processes and refocuses labour to more complex activities. So production efficiency increases.
Scheduling reduces time wastage by assigning time to complete activities.
