What is a distribution of means and how it differs from a population distribution?
One of the primary goals of constructing a frequency distribution for quantitative data is to summarize the data O by showing frequency of values that lie within a class or bin. O so that there are always 7 classes or bins of data. O ensuring that the classes or bins are always of different widths. O in a manner so that each class or bin has the same number of data points.
For the residents in 2014, use R to calculate the interval with 99% certainty that the interval contains the actual population mean of the residents by census tracts. Type in the interval with keyboard. We also know that in each year, the number of residents by census tract in the State of Maryland follows a normal distribution, and the variance in the number of residents within the State of Maryland is the same for different years.
