It is believed that average grade (based on a four-point scale) should have a positive linear relationship with university entrance exam scores. Given below is the Microsoft Excel output from regressing average grade on university entrance exam scores using a data set of eight randomly chosen students from a large university. Coeficients Standard Error Upper 95% 28398 t Stat P-value 0.5630 Lower 95% Intercept University entrance exam score 0.5681 0 9284 0.6119 -1.7036 0.1021 00356 2.8633 0.0286 00148 0.1895 If we test at 5% level of significance for a positive linear relationship between average grade and exam scores, which of the following is the correct conclusion? Select one: O The sample data does not provide evidence of a linear relationship between average grade and exam scores. O The sample data provides evidence of a linear relationship between average grade and exam scores. O The sample data does not provide evidence of a positive linear relationship between average grade and exam scores. The sample data provides evidence of a positive linear relationship between average grade and exam scores. The sample data does not provide evidence of a positive relationship between average grade and exam scores.
