2. The Weibull distribution, which is never mentioned in most statistics classes, will play an important role in this course. The Weibull is written (parameterized) in quite a few different ways, even in the same book. Here is the density of the Weibull from p. 16 of our text. for t0 where the parameters o and λ are both greater than...

In a box-and-whisker plot the upper edge of the box represents a. The 3rd quartile b. The 1st quartile c. The maximum d. The median e. The minimum
3. Six electronic controllers were tested under accelerated conditions and the following times to failure were observed: 46, 64, 83, 105, 123 and 150 hours. Do the following: a Determine how you would classify this data, that is individual, grouped, suspended, censored uncensored, and so on. Select rank regression (least squares) method on X as the parameter estimation miethod and determine the parameters for this data using the following distributions and plot the data for each distribution. From the plot,...
