(2 points) The area \(A\) of the region \(S\) that lies under the graph of the continuous function \(f\) on the interval \([a, b]\) is the limit of the sum of the areas of approximating rectangles:
$$ A=\lim _{n \rightarrow \infty}\left[f\left(x_{1}\right) \Delta x+f\left(x_{2}\right) \Delta x+\ldots+f\left(x_{n}\right) \Delta x\right]=\lim _{n \rightarrow \infty} \sum_{i=1}^{n} f\left(x_{i}\right) \Delta x $$
where \(\Delta x=\frac{b-a}{n}\) and \(x_{i}=a+i \Delta x\).
The expression
$$ A=\lim _{n \rightarrow \infty} \sum_{i=1}^{n} \frac{\pi}{8 n} \tan \left(\frac{i \pi}{8 n}\right) $$
gives the area of the function \(f(x)=\) on the interval

\(\mathrm{T}\) is a failure time following a Weibull distribution. Consider \(\mathrm{Y}=\log \mathrm{T}\) where \(\mathrm{Y}\) has an extreme value distribution with survival function$$ S_{Y}(y)=e^{-\epsilon^{\frac{n \mu}{\sigma}}} $$where \(-\infty<\mu<\infty\) is the location parameter and \(\sigma>0\) is the scale parameter. Expressing with parameters \(\mu\) and \(\varphi=\log \sigma\). Assume that failure times of subjects under study arise from Weibull distribution. Let \(x_{1}, \ldots, x_{n}\) be the observed failure or right censoring times for n subjects. Each subject i (i = \(1, \ldots, \mathrm{n}\) ) has...
