A mobile phone manufacturer wants to introduce a new feature in its latest model. Which statistical question should the company focus on to determine whether the feature will increase sales?

To determine whether the feature will increase sales, the company should measure customer interest in phones that include it. Finding what percentage of customers prefer the phone with the new feature directly indicates how appealing it may be to buyers. Battery life, manufacturing cost, and weight could matter for other decisions, but they do not directly measure customer preference.
