Use the rank correlation coefficient to test for a correlation between the two variables.

Ten luxury cars were ranked according to their comfort levels and their prices.

Make: A B C D E F G H I J K

Comfort: 5 8 9 10 4 3 2 1 7 6

Price: 1 7 3 5 4 2 10 9 6 8


Find the rank correlation coefficient and test the claim of correlation between comfort and price. Use a significance level of 0.05.

a. rank

b. critical values

c. accept or reject
