- Jack is a discus thrower and hopes to make it to the Olympics some day. He has researched the distance (in meters) of each men's gold medal discus throw from the Olympics from 1920 to 1964. Below is the equation of the line of best fit Jack found. y=0.34x+44.63y=0.34x+44.63 When calculating his line of best fit, Jack let x represent the number of years since 1920 (so x=0 represents 1920 and x=4 represents 1924). Using the line of best fit, estimate the distance Jack should be able to throw in order to be able to win the 2020 Olympics.By definition, the mean a is the center of gravity of the data. b is always the central (or middle) data point. c balances the number of observations on either side of mean value. d balances the deviations of the data from the mean. e Both (b) and (c) are correct f Both (a) and (d) are correct.Consider the following summary statistics of the variables x, y and z var(x) = 2.4, var(y)=3.2, var(z) =1.1 cov(x,y) = 3.1, cov(x,z) = 4.2, cov(y,z) = 8 What is the instrumental variable (IV) estimator of the effect of x on y when you use the variable z as an instrumental variable?
