A social media app is conducting a study on the amount of time users spend on theapp. They collect the following variables.Age Years: How old they are in years?Income: Monthly IncomeLocation: What country do they live in?Device: Do they use an iPhone, Samsung, other?Service: Who provides their mobile phone service? For example: T-Mobile, At&t,Verizon, ectHours: How many hours do they spend on the app per week.A) Think of 2 additional questions (a categorical and quantitative variable) the socialmedia app should include in their survey that may relate to how many hours theyspend on the app. Next to the variable write out the wording you suggest they use toask this question.Categorical:Quantitative:B) Come up with a research question that the app-maker could test using the variablesabove and a Chi-squared Hypothesis Test of independence/association. Write the nulland alternative hypothesis for your research questionVariables you use from above:Research question to be tested:Но:На: C) Which graph shows stronger evidence of a relationship with the number of hoursthey spend on the app?
