2. For determining the half-lives of radioactive isotopes, it is important to know what the background radiation is for a given detector over a certain period. A γ -ray detection experiment is conducted over 300 one-second intervals (sample g1). Generate the sample using the R codes below: set.seed(12345678) g1 = rpois(300,3) State the sample (g1) that you obtained. Do these look like observations of a Poisson random variable with mean λ = 3? To answer this question, do the following:...

Hi, I don't quite understand the solution to Chapter 10, Problem 62C of Data Structures and Algorithms in Java (6th Edition). The question is to design a variation of binary search for performing the get(k) operation on a sorted search table that includes duplicates. But what happens in step 1? is it a search for the first key value of k? In step 2, I don't understand what is being backtraced? The table? And why? In step 3, why are...

Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.02 m/s, due west. This average velocity results, because she hikes for 5.52 km with an average velocity of 2.22 m/s due west, turns around, and hikes with an average velocity of 0.663 m/s due east. How far east did she walk (in kilometers)? VE West East Number Units the tolerance is +/-2%
