Question Find a bar plot in the media or online. Include an image of the… Find a bar plot in the media or online. Include an image of the graph you found, not just the link. Hint: Google “bar plot,” “bar graph,” or “bar chart.” Choose a graph with a topic that is interesting to you since you will be using this graph for Parts 1 and II of this project. The vertical scale can be given in frequencies (count) or relative frequencies (proportions). Be sure that the graph is depicting real data, not made-up data.Identify the categorical variable being depicted.Answer questions:What is the most common category and least common category?What is the relative frequency for the most common category? Note: this is the value for  that you will use in part F. below.Conjecture the number of individuals in the most common category if there were 5,000 individuals included.Is there anything misleading about the graph? Give at least one way to improve the graph. Was a valid sampling method used to obtain the data? If so, explain and identify the name of the sampling method given. If not (or if this information is not given), describe a valid sampling method (in detail and in context) that could have been used and identify the name of the sampling method you described.Carry out a simulation for the most common category. Assume a sample of size 100 and . Complete 50 trials of the simulation using the RossmanChance applet at http://www.rossmanchance.com/applets/OneProp/OneProp.htm. Take a snip or screenshot of the resulting dot plot. Compute a two-sided p-value for the most common category in your graph. Based on your p-value, what is the appropriate conclusion for a test of these hypotheses: Math Statistics and Probability Share QuestionEmailCopy link Comments (0)
