Here is a question where you can see the usefulness of looking at a sample of size greater than 1. When people get on a roller coaster it is usually more than 1 person: *The maximum safe total weight for riding a particular roller coaster is 12,000 lbs. The roller coaster seats 60 people. If 60 males are riding the roller coaster, what is the probability that their mean weight exceeds 200 lbs? Note: 200 x 60 = 12,000 (the maximum weight capacity) Assume the mean weight of men in general is 194 lbs and standard deviation 68 Ibs. Always show your work.

A study was conducted to see of airbags save lives. The table below lists the results from a simple random sample of front-seat occupants involved in car crashes. Airbag Available No Airbag Available Occupant Fatalities 41 52 Total number of occupants 11,541 9,853 What is the sample proportion of fatalities where there were no airbags available, p2? What is the difference in the two proportions, D? What is the standard error of the difference, SED?
