Suppose you are playing a game and you get to roll 40 six-sided dice on your next turn. If you get a total of 160 or more from the 40 dice, you will win the game. Using sampling distributions, what is the probability that you will get a total of 160 or more with the 40 dice? Some useful things to know: When one six-sided die is rolled, the die roll (or number of spots showing) has a mean of 3.5 and a standard deviation of approximately 1.71.

8. An HP laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.57 ppm and a standard deviation of 3 ppm. A Brother brand printer can print an average of 17.21 ppm and a standard deviation of 4 pages and its printer speed is also normally distributed. You select 10 of each printer at random. What is the probability that mean Brother print speed is at least 2 pages faster than the mean HP print speed?
