3) A uniformly distributed continuous random variable, X, is described by the PDF shown. It is input into asystem producing a new random variable Y, described by the equation shown. Determine an expressionfor the CDF for Y as a function of fx(x). You do not need to solve non-trivial integrals. Just set them up.-2fx(x)1/42 xy= g(x)= |x|

Suppose that n observations are chosen at random from a continuous pdf fY(y). What is the probability that the last observation recorded will be the smallest number in the sample? I asked this question earlier today, but didn't quite understand all of the response. P(y1<=yn)p(y2<=yn) and so on was used, but shouldn't the yn be listed first in the inequality since we want to know if yn is the smallest?

Use the data in vapor.csv, obtain the transformed predictor 1/X, and the transformed response log(Y), where "log" refers to the natural logarithm. Denote the new predictor by X*(=1/X) and denote the new response by Y*(=log Y). Fit a least squares model for the new response and the new predictor.
