A high-end handbag designer is testing their latest handbag designs to improve sales. Version A features a slightly larger handbag, while Version B highlights a smaller-style handbag. The designer selects two groups, V1 and V2, to run an A/B test. Group V1 rates the larger bag and group V2 rates the smaller style. You can consider the rating to be on a scale of 1-10. Assuming a significance level of 0.01. Define a clear null hypothesis and alternative hypothesis for this A/B test. Identify the independent variable and the dependent variable.
