the average, what is the chance that the total time is more than 16 minutes? B) Is it reasonable to assume a normal distribution here? Why or why not?...

A) Assuming a normal distribution for the average, what is the chance that the total time is more than 16 minutes? B) Is it reasonable to assume a normal distribution here? Why or why not? C) Now give an integral equation (that you can approximate numerically) that gives the exact chance the total time is more than 16 minutes. 5) 6.14 Comment on the shape, what distribution is a reasonable t? 6) 6.30 Comment on the shape, same as the stef and leaf?
