Describe the sample size S and answer the question.

Suppose a worker may or may not be covered by healthcare. If he is covered, he may be under his employers healthcare plan or a different plan. In case of having another plan, it could be in his name or in his wife\'s name. Consider the experiment: choose randomly a worker and determine if he is covered and the type of coverage. Show work and offer detailed explanation please

Thanks

Solution

Sample size S

the worker that is randomly choosen and we need to determine if he is covered and the type of coverage

Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample. In practice, the sample size used in a study is determined based on the expense of data collection, and the need to have sufficient statistical power. In complicated studies there may be several different sample sizes involved in the study: for example, in astratified survey there would be different sample sizes for each stratum. In a census, data are collected on the entire population, hence the sample size is equal to the population size. In experimental design, where a study may be divided into different treatment groups, there may be different sample sizes for each group.

Sample sizes may be chosen in several different ways:
