This means that the multiple linear regression line is a much better line of fit for this data. 2. Ho: data follows normal distribution H1: data does not follow normal distribution P-value=.844 therefore fail to reject Ho

From the residual plot, it appears that the residuals are not randomly distributed, and the coefficient of determination if very small, therefore there does not appear to be a relationship between number of hours of sleep per night, and GPA. 4.
