A year ago your organisation invested R100 000 in a marketing campaign to improve its sales for a specific product. Given that money was diverted from product development, the organisation needed to make R500 000 in sales on the marketed product for the campaign to be considered a success
You have analysed the marketing data for your organisation for the last year looking at predictors of
sales and have obtained the following regression equation:
1.) What are the dependent and independent variables of the study?
2.) What kind of regression was conducted?
3.) With reference to your decision tree, specify the conditions under which this
form regression would be appropriate.
4.) What conditions would need to be satisfied for you to accept that the
possibility of bias in the beta values had been minimised?
