Proctors should walk around and make sure Hewlett-Packard calculators’ infrared ports are not facing each other. After 1 hour and 30 minutes, say: To calculate the probability, we use normalcdf (lower, upper, μ, σ n. σ n ) = normalcdf. ( E – 99,16 .7,17, 0. 8 30 ) ( E – 99,16 .7,17, 0. 8 30 ) = 0.0200. If the process is working properly, then the probability that a sample of 30 batteries would have at most 16.7 life span hours is only 2%.These are undoubtedly di erent answers. What happens if we try to calculate this probability using the third sample space? A simple event like this should have a certain probability of happening, and we should be able to calculate it.
