Problem 4b

Given information

Given: , where is the function whose graph is shown.

To find: We have to estimate for and  

Step-by-step explanation

We will estimate the area covered by the fuunction  for and by counting squares that comes under the curve of the function and observation.
i. To find for .

As from the graph, the area from to is  

Therefore,  

Now, since the graph of curve is smooth, we can only predict the approximate area by looking at the graph.

So,

unit²

where x is the cdf of random variable that follows exponential distribution with parameter 1.
