Which of the following interpretations is/are valid? I. A manager wants to predict the cost of travel for salespeople (in US$) based on the time spent (in dars on each sales trip. The following model has been developed: Y = 400 + 120x. If a salesperson did not take a trip (assuming it is within the x-data range), then the expected cost of travel for that sales person is $400. II. Regression analysis was applied to return rates of sparrow hawk colonies. A study on the relationship between return rate (x: % of birds that return to the colony per year) and immigration rate (y: % of new adult birds that join the colony per year) yielded the following regression equation: Y = 31.9-0.34x. Based on the estimated regression equation, if the return rate were to decrease by 1%, the rate of immigration to the colony would on the average increase by 0.34%.
