Aluminum bottles are reported to cool faster and stay cold longer than typical glass bottles. A small brewery tests this claim and obtains the following 90% confidence interval for the mean difference in cooling time (in minutes) for glass (sample 1) versus aluminum (sample 2): 2-SampTInt (38.08,44.72) Interpret this interval using 2 sentences. You can assume that all necessary conditions for the CLT are satisfied.
