Stuyvesant, yet another stats intern at corporate headquarters, wonders if that original claim by the executives is simply inaccurate, without further specifications. As a project, he collects from store sales receipts a simple random sample (SRS) of size 225. The sample mean for the weekly grocery purchases for a family of four is $196. He is defining as rare, or unusually extreme, any sample mean that is in either the bottom 1% or the top 1% of all possible sample means, for a total of 2%; hence, he is testing at the 2% level of significance. What conclusion should Stuyvesant draw, based on the available evidence? WHAT IS THE UPPER AND LOWER BOUND OF THE CONFIDENCE INTERVAL??
