You are doing a chi-square test of independence between class and grade given the following data collected (sample size is n=200).

The computed Chi-squared value for this table below is 6.8 (calculated ) and the value from the Chi-squared table with the correct degrees of freedom is 9.49 (critical value ) with a = 0.05.

Then, what will be your conclusion? (A MARKETING QUESTION)

Number of Students is shown in Each Cell	Class
I	II
Grade	A	14	6
B	25	15
C	60	20
D	34	6
F	17	3

A. fail to reject the null hypothesis and conclude that grade and class are independent

B. fail to reject the null hypothesis and conclude that grade and class are dependent

C. reject the null hypothesis and conclude that grade and class are dependent

D. reject the null hypothesis and conclude that grade and class are independent

E. it is too close to tell whether to accept or reject
