Question Use complete sentenced when appropriate, and show all work to… Use complete sentenced when appropriate, and show all work to receive full credit. 1.) [10 pts] The data set contains both qualitative (categorical) and quantitative (numerical) variables. Identify each of the eight variables from the dataset as either qualitative or quantitative by listing each one under one of the categories below. Qualitative Variables Quantitative Variables 2.) For this part, choose only one of the qualitative variables from the dataset to analyze. a.) [1 pt] Which of the qualitative variables did you choose to analyze? b.) [4 pts] Create a relative frequency distribution that summarizes the qualitative variable. c.) [5 pts] Create an appropriate graph that displays the qualitative variable you chose to analyze. Graphing by hand is just fine, but you are welcome to use any software you would like to create the graph. d.) [2 pts] For the qualitative variable you chose pick one of the possible values of the variable and calculate , the sample proportion of listings that have the value you chose (Example: if I was analyzing the “Neighborhood” variable, I could calculate the proportion of listings that were in Ballard). Hint: You already calculate sample proportions in part (b.)! Value you picked: = e.) [10 pts] Use your from part (d.) and calculate a 90% confidence interval for the true proportion of listings that have the value you chose (Example: if I calculated the proportion of listings in Ballard in part (d.), I would be constructing a 90% confidence interval for the true proportion of listings that were in Ballard). f.) [3 pts] Interpret your 90% confidence interval 3.) For this part, choose only one of the quantitative variables from the dataset to analyze. a.) [1 pt] Which of the quantitative variables did you choose to analyze? b.) [4 pts] Create a frequency distribution/table that summarizes the quantitative variable. c.) [5 pts] Create a histogram that displays the qualitative variable you chose to analyze. Graphing by hand is just fine, but you are welcome to use any software you would like to create the graph. d.) [2 pts] Based on your graph, how would you describe the shape of the distribution of the variable? e.) [3 pts] For the variable you selected, compare the mean to the median (both found at the bottom of the dataset). How do they compare? Does this seem reasonable given the shape of the dataset you found in your graph? (3 continued…) f.) [5 pts] For the quantitative variable you selected, use the 5-Number Summary (found at the bottom of the dataset) to test for any outliers. Are there any outliers within the dataset for the variable you chose to analyze? g.) [10 pts] For the quantitative variable you have chosen to analyze, use the sample mean and sample standard deviation (both found at the bottom of the dataset) to construct a 95% confidence interval for the true mean value of the variable. h.) [3 pts] Interpret your 95% confidence interval. i.) [2 pts] Did you find anything particularly interesting or noteworthy about the variable you chose to analyze? What kind of “takeaways” could you give someone about the quantitative variable you chose to analyze if they were not familiar with the dataset or statistics in general?
