5. In a large class of introductory Statistics​ students, the professor has each person toss a fair coin 11 times and calculate the proportion of his or her tosses that were heads. The students then report their​ results, and the professor plots a histogram of these several proportions.

​a) What shape would you expect this histogram to​ be? Why?

​b) Where do you expect the histogram to be​ centered?

​c) How much variability would you expect among these​ proportions?

​d) Explain why a Normal model should not be used here.

Issue 1: Pearson Correlation Coefficient One professor who teaches statistics gave students one homework assignment. He asked students to find a two-variable data set and compute the Pearson correlation coefficient. One student found a data set: one variable is students’ midterm test score in an introductory microeconomics class and total observations are 45 students; while the other one variable is also students’ midterm test score in another introductory microeconomics class and total observations are 57 students. Both of these two...
