Stacy Wood at the Moore School of Business in South Carolina is studying what people crave, familiar food or new food, during pe
riods of change in their lives. For her samples, those that self identified themselves as in a period of change, chose the new item 70% of the time, whereas students who self-identified themselves as not in a period of change, chose the new item 40% of the time. For the part that is listed in bold, what part of the field of statistics is this? a. description
b. design
c. inference
Description statistics is used to summarize sample or population by determining some of its parameters like mean, variance, standard deviation, proportion etc.
Stacy Wood at the Moore School of Business in South Carolina studied her samples and find sample proportions of a specific characteristic (proportion of people who chose new item) from two different samples of people who are identifying themselfves in a period of change and people who are not)
For example, if she further continues the study and finds with 95% confidence that proportion of people who are in a perid of change choses new item are higher than the proportion of people who are not in a period of change, then she would have made inferential statistics.
Because a normal deck of cards only has one eight of spades and only one of seven of heart. So that means the probability would be 2/52. Hope you get it!
