Question

All work is done in Excel and I have no idea how to draw the graph. Could someone please give me step by step instructions as to how to draw the graph. Also, if you could give Excel functions for how to solve the other equations that would be much appreciated.


Most computer languages include a function that can be used to generate random numbers. In Excel, the RAND function can be used to generate random numbers between 0 and 1. If we let x denote a random number generated using RAND, then x is a continuous random variable with the following probability density function.



a Graph the probability density function.

b What is the probability of generating a random number between 0.25 and 0.75?

c What is the probability of generating a random number with a value less than or equal to 0.3?

d What is the probability of generating a random number with the value greater than 0.6?

e Generate 50 random numbers by entering = RAND() int 50 cells of an Excel worksheet.
