C) Which of the following questions would the researcher not be able to explore using a 2 proportion z -test? Explain why. I. Are the app users in Mexico less likely to use an iPhone than the app users in Canada? II. Is the proportion of iPhone users different on T-Mobile than it is on Verizon? II. On average are iPhone users older than T-mobile users? D) The social media company know that older users are more likely to spend money on the app than younger users. They want to know which type of smartphone has older users. Write the null and alternative hypothesis the researcher would use to determine if there is a mean difference in the age of users who have iPhones versus Samsung phone users. E) State the name of the procedure you will use to conduct the hypothesis test. Explain why you selected this procedure and state your significance level here. F) Use the calculations below and your significance level from part E to write their conclusion in context. t Distribution with df = 29.3 Test Statistic: t=-1.853, P-value - 0.0740 10:920 0.0371 10.037 3. 3. 85

A social media app is conducting a study on the amount of time users spend on the app. They collect the following variables. Age Years: How old they are in years? Income: Monthly Income Location: 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, ect Hours: How many hours do they spend on the app per week. A) Which variable could the research construct a one proportion z-interval for? B) The social media app just launched a new algorithm that suggest content in an effort to increase the amount of time the user spends on the app. The researchers want to use the survey results to see if there is statistically significant evidence that on average users spend more than 10 hours per week on the social media app. The researchers found in their sample of 44 users, the mean hours spent on the app is 10.5 hours with a standard deviation of 5.675 hours. Which type of hypothesis test would they use? Explain.
