1 Nobel College Course: BBA BI 4 th HOME ASSIGNMENT ABK DATA ANALYSIS AND MODELLING 1. The managers of a brokerage firm are interested in finding out if the number of new clients a broker brings into the firm affects the sales generated by the broker. They sample 10 brokers and determine the number of new clients they have enrolled in the last year and their sales amounts in thousands of dollars. These data are presented in the table that follows: BROKER CLIENTS (X) SALES (Y) Calculation Shows that: ΣX = 260 ΣY = 480 ΣX² = 7594 ΣY² = ΣXY = SSX = 834 SST = 1236 SSE = a. State the regression equation and interpret the meaning of slope in this problem. What is the least square prediction for the amount of sales (in $1,000s) for a person who brings 25 new clients into the firm? b. Determine the coefficient of determination and explain its meaning in this problem. c. Compute 95%confidence interval estimate for the population slope β A food products company believes that storing frozen foods at low temperatures for several weeks might cause a noticeable weight loss in the products. Some data were collected to test this belief, as summarized in the table below: WEEKS STORED, X WEIGHT LOSS (%), Y Calculation shows: n = 8 ΣX = 242 ΣY = 9.78 ΣX 2 = 7436 ΣY 2 = ΣXY = SSX = SSY = SSE = a. Build a linear regression equation to represent the relationship between storage time and weight loss. b. What weight loss would the regression equation predict for this product if it were stored for low temperature for 28 weeks? What would be the 95% prediction interval estimate at this level of storage time (i.e. 28 weeks)? c. At 5% level of significance do a t-test for the slope. 3. The marketing manager of a large supermarket chain would like to determine the effect of shelf space on the sales of pet food. A random sample of 12 equal-sized stores is selected with the following results: STORE WEEKLY SALES, Y (HUNDREDS OF $) SHELF SPACE, X (FEET) Calculation shows that: X = 150 Y = 28.5 X² = 2250 Y² = XY = 384 SSE = e² = SSX = 375. a. Compute the coefficient of determination r², and interpret its meaning. b. At the 0.05 level of significance, is there evidence of a linear relationship between shelf space and weekly sales? c. Set up a 95% confidence interval estimate of the average weekly sales for all stores that have 8 feet of shelf space for pet food.

2 4. A financier whose specialty is investing in movie productions has observed that, in general, movies with big-name stars seem to generate more revenue than those movies whose stars are less well known. To examine his belief he records the gross revenue and the payment (in $ millions) given to the two highest-paid performers in the movie for ten recently released movies. COST OF TWO HIGHEST PAID PERFORMERS GROSS REVENUE X 2 Y 2 XY MOVIE (X) (Y) TOTALS a. What is the residual (error) term for an $8 million payment to the two highest paid performers? b. Compute the standard error of estimate S YX. c. At the 0.05 level of significance, conduct an overall fit of the model. 5. A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below: CITY PRICE ($) SALES Calculation shows that River Falls X = 12 Hudson Y = 390 Ellsworth X² = Prescott Y² = Rock Elm XY = 700 Stillwater SSX = 1.66 a. What is the estimated average change in the sales of the candy bar if price goes up by $1.00? b. What percentage of the total variation in candy bar sales is NOT explained by prices? c. Set up a 95% confidence interval estimate of the population slope β According to the Capital Asset Pricing Model (CAPM), the risk associated with a capital asset is proportional to the slope 1 (or simply beta [ ]) obtained by regressing the asset s past returns with the corresponding returns of the average portfolio called the market portfolio. (The return of the market portfolio represents the return earned by the average investor. It is a weighted average of returns from all the assets in the market.) The larger the slope of an asset, the larger is the risk associated with that asset. A beta ( ) of 1.00 represents average risk. The returns from an electronics firm s stock and the corresponding returns for the market portfolio for the past 15 years are given below.

3 MARKET RETURN (%) STOCK S RETURN (%) Year (X) (Y) X 2 Y 2 XY TOTALS a. Carry out the regression and find the beta ( ) for the stock. What is the regression equation? b. Does the value of the slope indicate that the stock has above-average risk? (For the purposes of this case assume that the risk is average if the slope is in the range 1± 0.1, below average if it is less than 0.9, and above average if it is more than 1.1.) c. If the market portfolio return for the current year is 10%, what is the stock s return predicted by the regression equation? Give a 95% confidence interval for this prediction.
