Final answer:
The statistical analysis that can be used is multiple regression analysis to determine the factors influencing sales in the first week of a new product launch.
Step-by-step explanation:
The tech company wanted to determine the factors influencing sales in the first week of a new product launch, so they identified 3 predictor variables and used a sample size of 8 product launches. In order to analyze this data, the statistical analysis that can be used is multiple regression analysis.
Multiple regression analysis allows the company to assess the relationship between the predictor variables (such as marketing spend, brand visibility, product features, etc.) and the dependent variable (sales in the first week). It helps determine the extent to which each predictor variable affects the sales and allows for prediction of future sales based on the identified factors.
By conducting multiple regression analysis, the tech company will be able to quantify the impact of each predictor variable on the sales and identify which variables have the strongest influence on the sales in the first week of a new product launch.
