Borrowers leave the issue desk of a small library according to a Poissonprocess with rate 40 per hour. The number of books issued to aborrower has a uniform distribution with probability mass functionx=1,2,..., 6.px(x)=(a) Calculate the mean and variance of the number of books issued bythe library to a borrower.The random variable S(t) denotes the total number of books issued inthe time interval (0, t], where t is measured in hours.(b) Calculate the mean and variance of the number of books issued ina morning (9 am-12 noon).(c) Calculate the index of dispersion for the random process{S(t); t >0}, and comment on what your value tells you about thepattern of book-borrowing at the library.

Assume a normally distributed population with a mean = 90 and standarddeviation = 12. Be sure to sketch the curves, include formulas & round appropriately. If you select one person at random from this population (M = 90, SD = 12)and find his/her score on this variable to be 68 would you be surprised/consider this score extreme (yes/no)? Why/why not? Be sure to show your work when justifying the answer.
