Researchers investigated the relationship of insider ownership, debt, and dividend policies in companies. One of their findings was that firms with high insider ownership choose lower levels of both debt and dividends. Shown here is a sample of data of these three variables for 11 different industries

Industry	Insider Ownership	Debt Ratio	Dividend Payout
Mining	8.2	14.2	10.4
Food and beverage	18.4	20.8	14.3
Furniture	11.8	18.6	12.1
Publishing	28.0	18.5	11.8
Petroleum refining	7.4	28.2	10.6
Glass and cement	15.4	24.7	12.6
Motor vehicle	15.7	15.6	12.6
Department store	18.4	21.7	7.2
Restaurant	13.4	23.0	11.3
Amusement	18.1	46.7	4.1
Hospital	10.0	35.8	9.0

Required;

(ii) Using the Excel Software, develop the equation of the multiple regression model to predict insider ownership by debt ratio and dividend payout.

(iii) Discuss the partial regression coefficients obtained in (ii) above

(iv) Predict the percentage changes in insider ownership of the company whose debt ratio is 50.5 and Dividend payout is 15.5.
