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 42 81
2 51 74
3 88 62
4 99 57
5 54 72
6 66 73
7 87 63
8 99 57
9 97 58
10 89 63
11 42 77
12 71 63
13 96 55
14 56 76
15 75 69
16 57 70
17 62 75
18 89 63
19 50 72
20 56 72
21 89 57

Step 1 of 2 : Using statistical software, estimate the parameters of the model

Second Test Grade=β0+β1(First Test Grade)+εi.

Enter a negative estimate as a negative number in the regression model. Round your answers to 4 decimal places, if necessary.
