(1 point) In the United States, voters who are neither Democrat nor Republican are called Independent. It is believed that 11% of voters are Independent. A survey asked 26 people to identify themselves as Democrat, Republican, or Independent. A. What is the probability that none of the people are Independent? (Hint: You can find this using the binomial distribution, or probability methods from Chapter 3) Probability = .04832 B. What is the probability that fewer than 5 are Independent? Probability = C. What is the probability that more than 3 people are Independent? Probability = 0.3193 Give your answers to at least 4 decimal places.You can complete this problem using either Minitab or Geogebra, but you will likely find the visualization of Geogebra easier to understand. Instructions are given here for Geogebra, but you can review the video "Using Minitab with the Binomial Distribution" in D2L under Content>Statistics Resources> Minitab Tutorials by Dr. Matos to see how to complete the problem using Minitab. Open Geogebra and choose "Probability Calculator." You can also get to this through the "View" menu. This opens in a new window (the online/app version may behave differently). The default is a Normal distribution with mean 0 and standard deviation 1 (the Standard Normal). Select Normal from the drop-down menu just below the graph, and choose "Binomial." The default is n = 20 observations/trials with p = 0.5 probability of success on each trial. From 8 - 12 success are highlighted, with total probability 0.7368. You might have to resize the bottom part of the display to see this. To the right of the graph, the probabilities for exactly k successes are shown. Click here for a screenshot. Part 1: Part 2: To find the probability that the number of success is within some range of values, select the correct type of interval (two-sided is the default) and enter the endpoint(s). Geogebra always includes the endpoint(s); how to get around this is shown in the next section. Keeping n = 20 and p = 0.5, compute the probabilities of the following. Use four decimal places, and do not convert to percent. . From 6 to 14 successes: Help me! . At most 9 successes: Help me! 10 or more successes: Help meStep by Step Solution
