At Generic Middle School, 8 students were sick with the flu on the first week of school. During the second week, 12 students were sick and on the third week, there were 18 students sick. The attendance clerk noticed that the number of students getting sick was growing exponentially with a growth factor of 1.5 week #1 week #2 week #3 week #10 ?? 12 18 If the models continues to be correct for at least the first 3 months, how many would be sick on the 10th week of school? O A. Approximately 308 students O B. Approximately 692 students O C. Approximately 205 students O D. Approximately 461 students
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
