The owner of a company would like to promote the use of public transportation. She decides to investigate how many miles her employees travel on public transportation during a typical day. The values for her ten employees (recorded to the closest mile) are shown below. 0 4 0 0 0 12 0 8 0 0 D a. Find the mean, median, and mode. b. She has just hired an additional employee. He lives in a different city and travels 95 miles a day on public transportation. Recompute the mean and median. Describe the effect of this outlier. a. The mean is The median is mile(s). (Round to two decimal places as needed.) mile(s). The mode is mile(s). b. Recompute the mean and median with the new employee included. Describe the effect of this outlier. The mean is mile(s). (Round to two decimal places as needed.) The median is mile(s). What effect does the outlier have on the mean and median? A. The outlier does not affect the mean or the median. B. The outlier affects the median but not the mean. C. The outlier affects both the mean and the median. D. The outlier affects the mean but not the median.
a. Explain the difference between categorical and quantitative variables. b. Give an example of a categorcal variable. c. Give an example of a quantitative variable. a. What is the difference between categorical and quantitative variables? O A. A variable is called categorical if each observation is measured numerically. A variable is called quantitative if observations on it represent different magnitudes of the variable. OB. A categorical variable is any characteristic observed in a study. A quantitative variable is the numerical value associated with each characteristic. OC. A variable is called categorical if each observation belongs to one of a set of categories. A variable is called quantitative if observations on it take numerical values that represent different magnitudes of the variable. OD. A variable is called categorical if each observation belongs to one of a set of categories. A variable is called quantitative if observations on it can be placed into one singular categorical group. b. Give an example of a categorcal variable. Select all that apply. A. Height B. Gender C. Religious affiliation D. GPA c. Give an example of a quantitative variable. Select all that apply. A. Education level B. Sex C. Weight D. Number of siblings
