    I don't understand how you got the -1.9599... in question 2a 4:53, you said you used the calculator but how???

      I am using a Casio Classwiz calculator which can give you the corresponding z value for any probability. You go to MENU, then 7-Distribution, then 3-Inverse Normal

    i don't understand why for q2 part c) we stop solving at 11231. profit = revenue - costs, we calculate revenue and not the profit. because we didn't subtract the costs of production per each length.

      Hi there. That's what we did. At the end of the line where we calculate the expected profit there is a minus 20 which is the cost.
