a.) Calculate the mean. The mean is $. (Round to three decimal places as needed.) b.) Calculate the median. The median is $: (Round to the nearest cent as needed.) c.) Determine the mode. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The mode(s) is/are $ (Type an integer or a decimal. Use a comma to separate answers as needed) O B. There is no mode for this data set. d.) Which of the three measurements would best describe the central tendency of this data? O A. The mean would be a better indicator of the central tendency of the exchange rate since there appear to be outliers. O B. The median would be a better indicator of the central tendency of the exchange rate since there appear to be outliers. OC. Both the mean and the median are accurate indicators of the central tendency of the exchange rate since there do not appear to be any outliers. O D. The mode is the better indicator of the central tendency of the exchange rate since this data is categorical. e.) Describe the shape of the distribution. Choose the correct answer below. O A. The data appear to be left-skewed because the mean is less than the median. O B. The data appear to be right-skewed because the mean is greater than the median. OC. The data appear to be symmetric because the mean is equal to the median.
