Use the P-value method to test =:H0β10 versus >:H1β10. Can you conclude that visual response is useful in predicting auditory response? Use the =α0.05 level of significance and TI-84 Plus calculator.
Compute the least-squares regression line for predicting auditory y from visual x. Round the slope and y-intercept values to at least four decimal places.
