a) Fit a model of anxiety as predicted by physical activity (write the prediction equation).

1.Prediction Equation: Anxiety = 99.54 +0.87 X (Physical Activity)

2.Prediction Equation: Anxiety = 99.54 -0.87 X (Physical Activity)

b) Explain residual versus predicted plot.

1.The plots (residual versus predicted value) show that there is no pattern suggesting specification of errors.

2.The plots (residual versus predicted value) show that there is some pattern suggesting specification of errors.

c) Test if your slope is significant (H0 = beta =0).

1.Since our P value <.0001 is less than alpha .05 we reject null and conclude that the slope different from this means there linear relationship between physical activity anxiety.>

2.Since our P value <.0001 is less than alpha .05 we fail to reject null and cannot conclude that the slope different from this means there no linear relationship between physical activity anxiety.>

d) What is the R² and Adjusted R²?

1. .81 and .79

2. .70 and .76

3. .81 and .70

4. .99 and .98

e) What would be the anxiety score of someone who has physical activity of 85?

1. 65.98

2.25.58

3. 98.75

4. 72.35
