observations each . These samples will be available to the two researchers , and we are going to plot how @ is distributed for different estimators There are two types of researchers in this world . Researcher _ uses as an estimator for 2 ,? 2 * 0 where @ corresponds to the sample mean of the sample he receives from us . Researcher 2 ? uses as an estimator 0? = 2 * )?0 (?0?@? @were ?)20 (? @ ? 0? corresponds to the median of the sample he receives from us . We have provided you this R code that has some information missing in case you need help for this exercise Question 8 What would be the mean of this distribution of ? Question 9 What would be the variance of the distribution of 2 2 ? Please enter the numerical value of the variance Note : Please review our guidelines on precision regarding rounding answers here . If you haven't already , please fill in the R code provided earlier We have run our simulations , simulating 100,000 different samples of size 100 . We have provided 200,000 researchers (A and B), each with one of these samples . They have sent us their estimators for @.?The following plot shows a histogram of their estimators (Figure 1). 0.8 0.6 0.4 02 0.0 Question 10 Does the blue histogram correspond to the estimator of researcher A or researcher B
