American Time Use Șurvey 20. Aluminum Bottles The aluminum bottle, first introduced in 1991 by CCL Container for mainly personal and household items such as lotions, has become popular with beverage manufacturers. Besides being lightweight and requiring less nackaging, the aluminum bottle is reported to cool faster and stav cold longer than typical glass bottles. A small brewery tests this claim and obtains the following information regarding the time (in minutes) required to chill a bottle of beer from room temperature (75°F) to serving temperature (45°F). Construct and interpret a 90% confidence interval for the mean difference in cooling time for clear glass versus aluminum. 11.3 Inference about Two Means: Independent Samples 557 Clear Glass Aluminum Sample size 42 35 Mean time to 133.8 92.4 chill (minutes) Sample standard deviation (minutes) 7.3
