(use both critical value and p-value methods). b) Apply ANOVA to determine if the mean response for Value for the Dollar is the same for different types of cell phones. c) Determine the preference for cell phone service providers among the gender. Can we conclude hat gender and cell phone service provider are independent? If not, what implications this have for marketing? d) Determine whether the three factors-signal strength, value for the dollar and customer service- significantly relate to the usage rate. Provide justification for your answer.
