1. After having estimated a regression model , we wish to forecast the value of given a new observation . We can consider two types of predictions: forecasting the conditional mean of , or forecasting the actual value of . What is true about the variances of these predictions? Var[conditional mean] > Var[actual value]. Var[conditional mean] = Var[actual value]. Var[conditional mean] < Var[actual value]. Var[conditional mean] may be larger than Var[actual value] in some data sets and smaller in others....

A juicer works for T amount of time before it breaks, where T
follows the exponential distribution with rate
= 3. After sales service examines the juicer at times distributed
according to a Poisson process with rate
= 2; if the juicer is found to be not working then it is
immediately substituted.
1) Find the probability that a juicer is examined at least 2
times before it stops working.
2) Find the expected time between replacements of juicers.
