Chapter 13.3, Problem 33E

a.

To determine

Find the predicted value of thrust efficiency y when the divergence angle is 20 and when x is 25.

b.

To determine

Find the estimated regression equation for the unstandardized model.

c.

To determine

Identify whether the cubic predictor should be deleted from the model.

d.

To determine

Explain what can be concluded about the relationship between SSE’s and R2's for the standardized and unstandardized models.

e.

To determine

Compute the R2 value for each model.

Identify whether the difference between the two R2 values convey that the cubic term could be deleted.

There is a linear regression: Yi = B0+ B1(Xi^2)+ ei present, where Xi is squared. ei ∼ N(0,σ2). How would I derive LSE for B0 and B1 and their variance?
When is the standard error of the estimate (in linear regression) large?       When the X values are very close to the Y values.     When the residuals are large on average.       When the average distance between actual Y scores and predicted Y scores is small.       When the coefficient of determination is small.
In running a regression of the retunrs of stock XYZ against the returns on the market, the Std for the returns of stock XYZ is 20% and that of the market returns is 15%. If the estimated beta is found to be 0.75 :  What is the maximum possible value of beta given that the standar deivation of the returns of stock XYZ is 20% and those of the market is 15% ?
