Exercise 4. Failure times (in years) for certain model of appliance follow a Gamma(2,4) distribution. Let X bethe failure time for the appliance you purchased, so X ~ Gamma(2,4).(b) What is the expected lifetime of your appliance, in months?(d) Use a Gamma calculator to compute the exact value of P(|Y – E(Y)| > 70).(e) Compute the 90th percentile of [the distribution of] Y.(f) True or False:24~x²(4). Explain.

Here's a table with average monthly price of a stock from Jan 2021-July 2021. Month Price Jan 29000 Feb 27000 Mar 31000 Apr 30000 May 32000 June 28000 July 29000 Using a 3-period weighted moving average with weights (wt, wt-1, W-2) = (0.6, 0.2, 0.2), the predicted price August is Using an exponential smoothing model with = 0.4, and with the initial predicted price for Jan the same as the observed price for January, the predicted price for August is % Now, let's suppose that we finally observe that the price for August is 30000. The absolute percent error (APE) of your prediction for August is using the weighted moving average method and % using the exponential smoothing model. (Note: Round your answer to the nearest 2 decimal places. For your APE answer for example let's say you get 0.06786 from Excel, then you should type-in 6.79 as your answer here since it is represented as percentage. Do not enter any symbols other than integers and decimal.)
