Suppose a researcher gathered survey data from 19 employees and asked the employees to rate their satisfaction on a scale from 0 to 100 ( with 100 being perfectly satisfied). Suppose the following data represent the results of the survey. Assume that the relationship with supervisor is rated on a scale from 0 to 50 (0 represents a poor relationship and 50 represents an excellent relationship); overall quality of the work environment is rated on a scale from 0 to 100 (0 represents poor work environment and 100 represents an excellent work environment); and opportunities for advancement is rated on a scale from 0 to 50 (0 represents no opportunities and 50 represents excellent opportunities).
Answer the following questions:
A) What is the regression formula?
B) How reliable do you think the estimates will be based on this formula? Explain your answer by citing the relevant metrics.

Investment analysts generally believe the interest rate on bonds is inversely related to the prime interest rate for loans; that is bonds perform well when lending rates are down and perform poorly when interest rates are up.
Use the following date to construct a scatter graph and then fit a regression line to the date. Report the regression formula and the r-squared values from the chart (right click on the data points, select Add Trend line, and selection options to show these metrics).
Do you think the bond rate can be predicted by the prime interest rate? Justify your answer using the relevant metrics.
