Eight movie releases — A, B, C, D, E, F, G, and H — are evaluated by two film critics, Sofia and Lucas. Each critic ranks the films from 1 (best) to 8 (worst) based on their artistic merit.

Rank	1	2	3	4	5	6	7	8
Sofia	E	A	G	B	H	D	F	C
Lucas	A	G	E	H	B	F	D	C

Calculate Spearman’s rank correlation coefficient for this data.

Stating your hypotheses clearly, test at the 5% level of significance whether or not there is a positive correlation between the artistic rankings of the two critics.
