A random sample of 3-person American families were asked how much money they spent on Christmas presents in 2023. The following descriptive statistics and box plot were generated: A. Calculate the lower and upper (outlier) fences. [4 points]B. Interpret the fences in a complete sentence and in the context of the problem. [2 points]C. In a complete sentence and in the context of this problem, interpret the median amount of money spent for this sample of 3-person families. [2 points]D. Calculate the Z-score for a 3-person family that spent $680. [Round to 2 decimal places; 2 points]NOTE: standard deviation = $135.E. Interpret the Z-score in a complete sentence and in the context of the problem. [2 points]
