The least squares regression line is Course Average \ = 64.15 + 0.31(Percent Attendance) a) Interpret the slope of the regression line in the context of the problem. b) Using the correct symbol, state the null and alternative hypotheses to determine if percent attendance is a useful predictor. As an alternative method for testing the null hypothesis, a simulation is conducted. Assuming the null hypothesis is true, we would be able to swap y values. After swapping the y values, a new regression line is fit and the slope is determined. The process is repeated 10,000 times and the file homework 5 top hat simulation contains the simulated slopes. Use the simulated slopes to approximate the p-value. Explain how you determined the p-value. At the 0.05 level, state the conclusion
