The amount of time that it takes for lidocaine to take effect after injection is uniformly distributed with a minimum of 44 seconds and a maximum of 103.9 seconds.

a. Sketch a diagram of the density function. What is the height of the function between the values of 44 and 103.9?

b. What is the probability that the time to take effect is between 52.93

and 91.14 seconds?

c. What are the values of the mean and standard deviation of this variable?

For any problem where you use a preprogrammed TI function, you must write down which function was used.
