You have determined that waiting times at a toll booth are uniformly distributed over the interval 20 to 60 seconds. what formula would you use in excel to generate random values in this range that follow the uniform distribution?

"=RAND()*(40) + 20"

Step-by-step explanation:

When we say that a random variable X follows an uniform distribution where a is the lower limit and the upper limit we are saying that each value on the interval (a,b) have the same probability of occur, and the density function is given by:

And for any other case.

For this special case we know that the random variable T="Waiting times at a toll booth" follows this distibution:

And we can use the excel to create random values on this range. So then the code to do this is given by:

"=RAND()*(b-a) + a"

"=RAND()*(60-20) + 20"

"=RAND()*(40) + 20"

practice. practice. practice.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
