This interests us to know which of the states in U.S. are buying more cigarettes and to know on an average what would be the sales of cigarettes in total United States.
The data set is shown in Excel Sheet for your reference.
2. Choose a legitimate sampling strategy and collect at least 30 data points using your created question or topic. Discuss the sampling strategy in sufficient detail so that someone else could repeat your data collection without any difficulties or questions.
To know about the cigarette sales, the data has been collected in every state of United States. In every state 30 shops has been selected and the sales of cigarettes per capita is collected. And average per capital sales for these 30 shops was found.
