A researcher has data and wants to fit the following linear model:     i.e.  a linear regression model without an intercept parameter.  Here, are independent and each as usual.  Define .   Then the correct expression for the least-squares estimate of for this model is given by:

Suppose that x is the length and Y is the weight of smallmouth bass (a type of fish) in a large Texas lake.  A sample of smallmouth bass was caught at this lake and a simple linear regression model for Y verses x was fitted using the observed data.  Using all the results we studied in class regarding inference for simple linear regression, the following two intervals were produced, one of which is a 95% confidence interval for the average weight (in pounds) of smallmouth bass that are 14 inches long, and the other is a 95% prediction interval for the weight (in pounds) of a particular smallmouth bass that is 14 inches long:   Which of the following is correct?

The residual plot below was obtained from a polynomial regression analysis.     From this plot we can see that:

Suppose that a Golden Retriever is defined to be ‘large’ if she is at or above the 80th percentile of the weights for dogs of her age.  Then, what is the smallest weight that qualifies a 9 month old female Golden Retriever as ‘large’? The needed z-score would be 0.8416
