Please do not give solution in image formate thanku. Define a conditional median of Y given X = x to be any median of the conditional distribution of Y given X = x. Suppose that we will get to observe X and then we will need to predict Y. Suppose that we wish to choose our prediction d(X) so as to minimize mean absolute error (MAE), E(|Y − d(X)|). Prove that d(x) should be chosen to be a conditional median of Y given X = x. You can use the fact that for a univariate random variable MAE is minimized at the median, m.
Suppose that 95% of the bags of certain fertilizer mix weigh between 49 and 53 pounds. Averages of three succesive bags were plotted, and 47.5% of these were observed to lie between 51 and X pounds. Estimate the value of X. State assumptions you make and say whether these assumptions are likely to be true for this example.
