Answer:
Variance = 0.02141851
Explanation:
We first calculate the mean for the stocks
Mean = (0.1858 - 0.0558 + 0.2081) / 3
Mean = 0.3381 / 3
Mean = 0.1127
Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1
Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2
Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2
Variance = 0.04283702 / 2
Variance = 0.02141851
The variance of returns is 0.02141851
Answer:
E. Cluster
Explanation:
Cluster sampling is a type of sampling method in which the population under study is divided into different groups known as clusters before simple random samples are selected from each population clusters. The analysis of such population is carried out based on the sampled clusters.
This method is adopted when a researcher does not have access to the whole population under research.
Advantages of cluster sampling.
The research method only needs fewer resources.
The sample under review is feasible.
Note: Cluster sampling is not as accurate as simple or stratified random sampling.
