A statistics professor would like to build a model relating student scores on the first test to the scores on the second test. The test scores from a random sample of 21 students who have previously taken the course are given in the table. Test Scores Student First Test Grade Second Test Grade 1 70 51 2 74 93 3 61 71 4 48 55 5 64 47 6 62 73 7 78 57 8 85 57 9 70 73 10 95 83 11 80 68 12 86 52 13 95 80 14 88 91 15 64 51 16 91 89 17 81 51 18 75 95 19 52 67 20 63 47 21 86 70 Find the value of the test statistic for testing whether there is a linear relationship between the two test grades. Round your answer to two decimal places, if necessary.
