" Am I right - 20Qs?" Introduction to Binomial Distribution Model Part 1 ) Probability Distribution” “Experimental number of question Correctly Answered X: x Pe (X=x) 1. Draw the distribution graph as a dot plot. What do you notice from the What do you wonder? 2. Estimate the mean and the standard deviation of the probability distribution for the number of correctly answered questions: 3. Calculate the mean and the standard deviation of the probability distribution for the number of correctly answered questions. 4. Find the probability that a) Exactly 5 questions correctly answered. P(X= 5) = b) At least 5 questions correctly answered. c) More than 5 questions correctly answered. d) Less than 5 questions correctly answered. Part 2 ) Modelling Probability Distribution using Binomial Model Use Binomial distribution to model the probabilities of guessing 20 questions. Binomial model requires Two (Bi) parameters to calculate the model estimates of the probabilities.
