Question 5 (Interpretation of Stata output), 10 points

A study investigated the relationship
between audit delay (Delay), the length of time from a company’s
fiscal year-end to the date of the auditor’s report, and variables
that describe the client and the auditor. Some of the independent
variables that were included in this study follow:

Industry A dummy variable coded 1 if the firm was an industrial
company or 0 if the firm was a bank, savings and loan, or insurance
company.

Public A dummy variable coded 1 if the company was traded on an
organized exchange or over the counter; otherwise coded 0.

Quality A measure of overall quality of internal controls, as
judged by the auditor, on a five-point scale ranging from
“virtually none” (1) to “excellent” (5).

Finished A measure ranging from 1 to 4, as judged by the
auditor, where 1 indicates “all work performed subsequent to
year-end” and 4 indicates “most work performed prior to
year-end.”

A sample of 40 companies provided the
following data:

1) Develop the estimated regression equation using all of the
independent variables.

2) Estimate the significance of the model.

3) Estimate the significance of each slope. Calculate t-stat for
industry variable.

4) Did the estimated regression equation developed in part (a)
provide a good fit? Explain.

5) Give recommendations to the analyst how he could improve the
model.

PLEASE, PROVIDE VERY DETAILED ANSWER
