What is meant by random? Explain what a run is.
Step 1 of 5) What is meant by random Explain what a run is. Describe the Distribution of the Sample Mean: Nonnormal Population Now we explore the distribution of the sample mean assuming the population from which the sample is drawn is not normal. Again we use simulation. Sampling from a Population That Is Not Normal Problem The data in Table 1 represent the probability distribution of the number of people living in households in the United States. Figure 6 shows a graph of the probability distribution. From the data in Table 1, we determine the mean and standard deviation number of people living in households in the United States to be m = 2.9 and s = 1.48. Clearly, the distribution is not normal. In fact, the random variable is discrete! Approximate the sampling distribution of the sample mean x by obtaining, through simulation, 1000 samples of size (a) n = 4, (b) n = 10, and (c) n = 30 from the population.
