exif: {"Image DocumentName": "Tests on the slope for straight line regression", "Image ImageDescription": "Consider the simple straight line case. We often test the null hypothesis that the slope is equal to zero which is equivalent to X has no effect on Y ! Or in statistical terms : X has a negative effect. Ho: vs Ha: X has a significant effect. X has a positive effect. The test is computed using. the t-statistic. With t-distribution with n-2 degrees of freedom!", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
