Consider a discrete random variable, X having the following probability function. f(x)= [(x+6)/20] for x\varepsilon{-4,0,6}
Let x1, x2, and x3 be independent binary random variables taking 1 with probability p and zero with probability 1-p. Define two estimators p hat 1 = x bar and p hat 2 = (xbar/2) + (1/4), where xbar = (x1 + x2 + x3)/3.

One of the most common causes of inaccurate melting points istoo rapid heating of the melting point bath. Under these circumstances, how will the observed melting point compare to the true melting point?
Use the variable GRASS as your independent or grouping variable (1 = legal; 2 = not legal). Investigate whether there is a significant difference between these two groups in terms of their age (AGE), number of children (CHILDS), and education (EDU
