True or False? The normal distribution model is an important probability distribution model that is appropriate when a particular experiment or process results in a continuous outcome. True or False? In Simple random sampling, each member of the population is assigned a unique identification number, and then a set of numbers is selected at random to determine the individuals to be included in the sample.
