(e) Suppose that 4 balls are placed sequentially into one of 5 bins, where the bin for each ball is selected at random. For i = 1, 2,3,4,5, define the indicator variables 1, if the ith bin is empty; 0, otherwise Xi _ Then the number of empty boxes is given by X = X\+X2+ X3 + X4+X5, and we learned from week #7 lecture notes and midterm II that Xi ~ Bernoulli(p) with p = (1 - 2)4 =...

4. The anscombe data set in the datasets R package (should automatically be loaded) contains 4 pairs of response-explanatory variables. The pairs are xl-yl, x2-y2, x3-y3, and x4-y4 where x is the explanatory variable and y is the response variable. (a) Run 4 simple linear regression analyses (one on each of the 4 pairs) to verify that the regression output is exactly the same (up to numerical accuracy) b) For each pair, describe what is wrong (if anything) and use...
nsider the following expression 8.50x10-5-x(0.100 +x)2 We can solve for x using a technique called successive approximations. Step 1: If we assume that x is very small compared to 0.100 (such that 0.100 + x 0.100) then our first approximation of x (let's call it x) can be calculated as 8.50 × 10-5-XI (0.100) 2 Number Express all answers to three or more significant figures Step 2: Now, take your first approximation of x and plug it into the full...
