Psychology: Testing An army psychologist gave a random sample of seven soldiers a test to measure sense of humor and another test to measure aggressiveness.

Higher scores mean greater sense of humor or more aggressiveness.

Soldier 1 2 3 4 5 6 7 Score on humor test 60 85 78 90 93 45 51 Score on aggressiveness test 78 42 68 53 62 50 76

(i) Ranking the data with rank 1 for highest score on a test, make a table of ranks to be used in a Spearman rank correlation test.

(ii) Using a 0.05 level of significance, test the claim that rank in humor has a monotone-decreasing relation to rank in aggressiveness.
