Within statistics a confidence interval gives us the percentage probability
that an estimated range of possible values in fact includes the actual value
being estimated (Small Business, n.d.). Within the business aspect article

The normal distribution is the most important and most widely used
distribution in statistics. It is sometimes called the bell curve, although the
tonal qualities of such a bell would be less than pleasing (n.d., Introduction
to Normal Distribution).

Probability refers to the likelihood or relative frequency for something to
happen. The continuum of probability falls anywhere from impossible to
certain and anywhere in between. When we speak of chance of the odds; the

The sampling concept is defined as the process by which members of a
population are selected for a sample (Levine & Stephan, 2005). Sampling is
always pondered as to why we study them and use them in conjunction with
populations. Well, samples are prefera
