Question

The table below gives the number of parking tickets received in one semester and the GPA for five randomly selected college students who drive to campus. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting the GPA of a college student who drives to campus based on the number of parking tickets they receive in one semester. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant. Number of Tickets 3 4 5 6 7 GPA 3.7 3.5 2.1 1.8 1.6 Table Step 4 of 6 : Determine the value of the dependent variable yˆ at x=0.

Answer 1

The statistical software output for this problem is :

Step 4 :

The value of the dependent variable yˆ at x=0 is 5.49
