Questions 4-7: A statistics teacher gave each of her students a spinner with four equal sized sections: one red, one blue, one yellow, and one green. She asked each of them to spin their spinner 50 times, record the proportion of times their spinner landed on red, and add the value to a class dotplot. They repeated this process until they had a plot with many dots, with each dot representing a sample proportion (Pre ) from a spinner that is 25% red. Where would you expect the class dotplot to be centered? Hint In other words, what would the mean of the sampling distribution be? You learned how to describe the sampling distribution of a sample proportion in In-Class Activity 9.C. Question Help: Message instructor Calculator Submit
