Statement I: If a dataset has enough data points, then it is sufficient to draw conclusions about the population from which it was drawn.
Example: A dataset with 100 observations would be sufficient to determine the mean and standard deviation of a population, even if the data has some missing values.
Statement II: If a dataset has enough data points and is representative of the population being studied, then it is sufficient to draw conclusions about the population from which it was drawn.
Example: A dataset of randomly selected individuals living in a certain area would be sufficient to draw conclusions about the average income of individuals in that area, even if the data is not representative of the entire population
