You are a data analyst working for a food magazine in Austin, Texas. The magazine is planning a special feature on the booming barbecue scene in Austin, highlighting how much brisket, a Texan delicacy, is sold by popular local joints. To provide readers with an accurate picture of the barbecue culture, your editor has asked you to estimate the average weekly weight of brisket sold by these establishments. You have collected a sample data set on the weight of brisket (in pounds) sold weekly by different barbecue joints in Austin. Using this data, estimate the average amount of brisket sold per week in local barbecue joints. Use a 99% confidence level for your estimate.Specify your answer rounded to the nearest integer.  Here is the sample data you collected: 250, 275, 300, 320, 290, 310, 330, 345, 360, 380, 295, 315, 305, 335, 355, 340, 325, 280, 290, 310   Left bound = [leftbound]Right bound = [rightbound]
