1. The ranks of 10 students in Mathematics and Physics are given:
Math: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Physics: 2, 1, 4, 3, 5, 7, 6, 10, 8, 9
Find the Spearman’s rank correlation coefficient and comment.

2. Two judges rank 8 projects in a competition as follows:
Judge 1: 1, 3, 2, 4, 5, 6, 7, 8
Judge 2: 2, 1, 4, 3, 6, 5, 8, 7
Calculate the rank correlation coefficient and test its significance at 5% level.
