Consider the following contingency table of observed frequencies:

Column Variable
Row Variable	C1	C2	C3
R1	3	12	5
R2	18	17	15
R3	10	20	0

Part A: Identify the null and alternative hypotheses for a chi-square test of independence based on the information in the table.

Part B: Calculate the expected frequencies for each cell in the contingency table.

Part C: Calculate the chi-square test statistic

Part D : Determine the Chi-square critical value , using alpha =0.01 state your conclusions.
