Question

In a review journal, a group of university researchers investigated the lucky store effect theory in lottery ticket sales, which is the theory that a lottery retail store that sold a large-prize-winning ticket will experience greater ticket sales the following week. The researchers examined the weekly ticket sales of all 24,200 active lottery retailers in a region. The analysis showed that "the week following the sale of [a winning Lotto ticket], the winning store experiences a 14 to 39 percent relative sales increase..." Consequently, researchers project that future winning lottery retail stores will experience the lucky store effect. Is this study an example of descriptive statistics or inferential statistics? Explain. Choose the correct answer below. A. The study is an example of inferential statistics because it is using sample data to make a prediction. B. The study is an example of inferential statistics because it utilizes numerical methods to explore the sample and summarizes the information revealed, to present the information in convenient form. C. The study is an example of descriptive statistics because it is using sample data to make a prediction. D. The study is an example of descriptive statistics because it utilizes numerical methods to explore the sample and summarizes the information revealed, to present the information in convenient form.
