We want to find out if the number of hours students work on a TMA can predict their marks. To investigate this research question, we collect data on how long students worked on a TMA and what mark they achieved. We use Simple Linear Regression to build a regression model and analyse the data.

Our results show that the average student worked for 23 hours on their TMA and that students achieved, on average, 72.53% as a mark. We also know that the intercept of our model is 64.63 and the slope 9.64. What would our regression equation for this data look like? Select one:

-Y = B0 + B1x + -Y = 64.63 + 23x + -Y = 72.53 + 9.64x + -Y = 64.63 + 9.64x +
