Bottles for room spray are supposed to weigh exactly 16 oz. Inspectors want to develop process controlcharts. They take six boxes of five bottles each and weigh them. They obtain the following data. The meanweights of each of the 6 samples are 14.6, 16.5, 18.1, 13.2, 16, and 14.8 respectively. Likewise, the rangevalues for the each of 6 samples are 0.7,0.5,0.4, 0.2,0.4, and 0.9 respectively.

According to data from the Tobacco Institute Testing Laboratory, a certain brand of cigarette contains an average of 1.4 milligrams of nicotine. An advocacy group questions this figure, and commissions an independent test to see if the the mean nicotine content is higher than the industry laboratory claims. The test involved randomly selecting n = 15 cigarettes, measuring the nicotine content (in milligrams) of each cigarette. The data is given below: 1.8, 1.8, 1.5, 1.1, 1.4, 1.3, 1.3, 1.4, 1.1, 1.3, 1.6, 1.2, 1.8, 1.4, 1.6; Download .csv file Not sure how to perform some of the tasks with R-Studio?
