A series of experiments was conducted to measure bubble diameter. Three characteristics x1, x2, and x3 were varied for each experiment. The data obtained are listed in the below table.

Consider the multiple regression model that relates bubble diameter to x1, x2, and x3.
What would be the bubble diameter for x1=5.9, x2 =0.9, and x3=11.5

(a) Consider three positive integers, x1, x2, x3, which satisfy the inequality below: x1 +x2 +x3 =17. (1) Let’s assume each element in the sample space (consisting of solution vectors (x1, x2, x3) satisfying the above conditions) is equally likely to occur. For example, we have equal chances to have (x1, x2, x3) = (1, 1, 15) or (x1, x2, x3) = (1, 2, 14). What is the probability the events x1 +x2 ≤8occurs,i.e.,P(x1 +x2 ≤8|x1 +x2 +x3 =17andx1,x2,x3 ∈Z+)(Z+...
