4.4.1 Practice: Assignment Practice Probability and Statistics Sem 2 Points Possible:20 Name: Sivan Kanitz Date: Answer the following questions using what you've learned from this unit. Write your responses in the space provided. Scoring: Each correct answer is worth 1 point. Where calculations are needed to find the answer, you must show your work to receive credit. For questions 1 - 2, use the density graph to perform the calculations. It takes Lee anywhere from 10 to 14 minutes to walk to the store, with all the times in that range being equally likely. Here is the density graph of the time distribution for Lee's walk. 1. What is the height of the shaded rectangle in the density graph? Answer choices: 0.25 0.50 0.75 1.00 2. What is the probability that Lee will take between 11 minutes and 12.5 minutes to walk to the store? Answer choices: 18.75% 25% 31.25% 37.5% For questions 3 - 5, use the density graph to calculate the requested probabilities. Mrs. Adams just gave the final exam for the Government course she teaches. Here's the density graph of the distribution of scores students earned on her final. 3. What is the probability of randomly choosing
