Answer:

No answer provided yet.Well, not really. You make inferences about the mean of a population with the Chi-Square distribution when the data is categorical in nature (counts). It is also used to test categorical associations or to the goodness of fit for data to a model. For categorical data you need the counts, which allow you to generate means and standard deviations, the standard deviation of the sample data is an estimate of the unknown population standard deviation.
