Updating mean and variance estimates baby cash money dating

After the Analysis of Variance section, there is a section titled Parameter Estimates.What is the interpretation of the values listed there, the 30, 19 and -10?

Let’s make a data file called dummy2 that has dummy variables called iv1 (1 if iv=1), iv2 (1 if iv=2) and iv3 (1 if iv=3).The parameter estimate for iv1 is the mean of group 1 minus the mean of group 3, 49 – 30 = 19, and indeed that is the parameter estimate for iv1.Likewise, the parameter estimate for iv2 is the mean of group 2 – the mean of group 3, 20 – 30 = -10, the parameter estimate for iv2.In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] parametrized by two positive shape parameters, denoted by α and β, that appear as exponents of the random variable and control the shape of the distribution.The beta distribution has been applied to model the behavior of random variables limited to intervals of finite length in a wide variety of disciplines.
