I have a data set (n=100) with hormone concentrations and the frequency of each value. I have found the mean, the sample variance, and the standard deviation. Assuming normal (continuous) distributions, I'm asked to determine the parameters of the continuous probability distribution functions. How would I go about doing so? Thank you!
