Research on the number of COVID-19 confirmed cases in your province by city/municipality. Suppose that 5 cities and/or municipalities are drawn as samples. A. What is the mean number of COVID-19 confirmed cases in your province? How about the variance and standard deviation of this population? B. Construct a sampling distribution of the sample mean. What is the mean, variance and standard deviation of the sampling distribution of the sample mean? C. Does the sample statistics obtain in (B), a good estimate to the population parameters in (A)? Why or why not?
