Consider the zero intercept model given by Yi = B1Xi + ei (i=1,…,n) with the ei normal, independent, with variance sigma^2. For this mode (i) find the sum of (Yi –Yi-hat). (ii) find the sum of (Yi – Yi-hat)Xi. (iii) find the estimator of the error variance, sigma^2. (iv) is the estimator of the error variance biased?

Suppose you have 3 cards: 1. A red card is red on both sides. 2. A blue card is blue on both sides. 3. A mixed card is red on one side and blue on the other. You gather the cards and toss them into a hat. You then select one randomly from the hat and place it on the table. Given that the side facing up is blue, what is the probability that the other side is also a...
