Question

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  denote a random number generated using RAND, then  is a continuous random variable with the following probability density function.

 

a.  Select the probability density function.

 

1.    
2.    
3.    
4.    

 

Choose the correct graph from above:

b.  What is the probability of generating a random number between 0.25  and 0.75  (to 1 decimal place)?

 

c.  What is the probability of generating a random number with a value less than or equal to 0.3  (to 1 decimal place)?

 

d.  What is the probability of generating a random number with a value greater than 0.6  (to 1 decimal place)?

 

e. Using 50  random numbers given below, compute the mean and standard deviation.
