5 Using a=.1, what is your conclusion about how professor A and professor B rank the twelve students?

a. Since the P-value is less than .1, we can conclude that the ranking of the student by professor are correlated

b. Since the p-value is less than .1, we can conclude that the ranking of the student by professor are not correlated

c. Since the p-value is greater than .1, we can conclude that the ranking of the student by professor are correlated

d.Since the p-value is greater than .1, we can conclude that the ranking of the student by professor are not correlated

e. The ranking is independent and cannot be compared to each other

6 Using a=.05, what is your conclusion about how professor A and Professor B rank the twelve students

a. Since the p-value is less than 0.05, they are correlated

b. Since the p-value is less than 0.05, they are not correlated

c. Since the p-value is greater than 0.05, they are correlated

d. Since the p-value is greater tha 0.05, they are not correlated

e. Independent and cannot be compared to each other
