Answer:
This is a stratified random sample because a separate random sample is selected from each class
Explanation:
Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.
After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.

Explanation:
Zone of tolerance with respect to a service refers to, the acceptable range to a customer, that lies between the perceived desired level of service expected and the minimum level of service acceptable.

If the service received lies in the zone of tolerance, the customer would be satisfied. If it is higher than the desired level, the customer would consider it exceptional.
In case the service received falls below the minimum level of acceptance, the customer would be disappointed and feel deceived or tricked.

It is well-known that the risks from stock are higher than the risks from bonds. As a result, the stock investments always attract higher returns and less tax, as the investor can postpone the tax for a longer term. Again, stock investments can be for the long-term unlike bonds that have defined periods.
The advantage of a free market economy is that when it works it can both be reward and perpetuate innovation But they are inherently more risky and does tend to favor those more capital and resources . In an Economic make system with multiple equilibria coordination failure occurs when a group of firms could achieve a more desirable equilibrium but fail to because they do not coordinate their decision making
