You are a data analyst working for a popular lifestyle magazine in Seattle, Washington. The magazine is planning a special feature on the coffee culture in Seattle, highlighting the daily coffee consumption in local cafés. To provide readers with an accurate picture, your editor has asked you to estimate the average daily coffee consumption (in ounces) sold by these cafés. You have collected a sample data set on the daily coffee consumption from various cafés in the city. Using this data, estimate the average amount of coffee sold per day in local cafés. Use a 99% confidence level for your estimate. Specify your answer rounded to the nearest integer. Here is the sample data you collected: 295000, 300000, 285000, 320000, 290000, 310000, 315000, 280000, 305000, 300000, 295000, 310000, 300000, 285000, 275000   Left bound = [leftbound]Right bound = [rightbound]

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]
