To enhance your understanding of the variance of dincrete random variable, answer the probleme that follow in your answer sheet. 1. Despite the pandemic, godparents atill give cash gifta to their godchildren amounting Php100, Php200, Php500 and Phpl 000 with the following probabilities 04, 0.3, 0.2, and 0.1 respectively Compute and interpret the variance of the given data 2. In retrieving the outputs of the learners in this Modular Distance Learning, a senicr high school teacher recorded the following data. Compute and interpret the variance of the random variable. No. of students who did NOT submit (x) Probability (Px) 0.4 0.3 0.2 3. 0.1
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!
