*There are two different answers posted. Other students were asked the same question. Which response is correct? Thank You :0) The population of drivers has a μ = 10 and σ = 20 speeding tickets. If we randomly select (with replacement) a sample of n=400 from the population, how well (on average) will the sample represent the population? In other words, how far off (on average) will you expect your sample mean to be from the population mean? 1. 0.05...

6. (11 marks). Students sometimes compare different instructors teaching the same course and claim that one instructor is harder than another. The Department of Mathematics at the University of Kazoo decided to test this claim. They asked two different calculus instructors, Dr. Reimann and Dr. Poincaire, to prepare final exams and 20 volunteer students who had already passed calculus with other instructors to write both exams (one in the morning and one in the afternoon). The students grades were then...
