Health insurance has been identified as an effective tool for removing barriers to healthcare utilisation especially in developing countries. However, many factors such as education, wealth or income, age, religion, health status and sex can influence individual’s decision toe enrol or not to enrol onto health insurance. The National Insurance Commission (NIC) of Ghana aims to evaluate health insurance policy subscription among individuals in a typical rural district of the country (Biakoye). The distributions of individuals in all the five communities of the district are as follows: Ahenkro 12,800; Bumbula 3,200; Wurupong 6,400; Appiakrom3,200 and Ntumda 6,400. You have been contracted to work on this project. The aim of this project is to ascertain the association between religious denominations and health insurance enrolment decisions. a. Choose and describe appropriate sampling technique(s) to be adopted in selecting a representative sample of 24,000 individuals for the study?
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
