this is one question, pls help by answerjng all parts for a thumbs up, thank you so much for your help.

The following set of data is from a sample of n=6. 4 2 5 4 7 12 O a. Compute the mean, median, and mode. b. Compute the range, variance, standard deviation, and coefficient of variation. c. Compute the Z scores. Are there any outliers? d. Describe the shape of the data set. a. Compute the mean, median, and mode. Mean=(Type an integer or decimal rounded to four decimal places as needed.) Compute the median Median = (Type an integer or a decimal. Do not round.) What is 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. Do not round. Use a comma to separate answers as needed.) B. There is no mode for this data set. b. Compute the range. Range = (Type an integer or a decimal. Do not round.) Compute the variance. s2 = (Round to three decimal places as needed.) Compute the standard deviation. S = (Round to three decimal places as needed.) Compute the coefficient of variation. CV = % (Round to three decimal places as needed.) c. Compute the Z scores. (Round to three decimal places as needed.) Data (x) Z Score 4 2 5 4 7 12 Are there any outliers? 0 Yes d. What is the shape of the data set? O Positive (right-skewed) because the mean is greater than the median O Symmetric because the mean is equal to the median O Negative (left-skewed) because the mean is less than the median
