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 2121students who have previously taken the course are given in the table.

2	9292	8383
3	9595	8484
4	7777	7373
5	7272	7272
6	4040	5757
7	6464	7070
8	6565	7474

Step1of2:

Using statistical software, estimate the parameters of the model

Second Test Grade=0+1(First Test Grade)+iSecond Test Grade=0+1(First Test Grade)+.

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