You work in Social Media as a consultant. You are working on a new report to examine trends in Social Media usage and age. You conducted a survey of 1072 people randomly selected in the United States (you limited the minimum age to 12). The file "Usagef.xlsx" has the results of the survey. For each Social Media platform, you have a 0/1 variable indicating whether or not the person said they used the platform in the last 6 months. For each of those variables, 1 means the person did use the platform in the last 6 months, and 0 means they did not. You also have the age of each respondent calculated based on birth date (so 43.56 means the individual is 43.56 years old). There are two additional variables:

Young adult: 1=respondent is under 35; 0=respondent is 35 or over.

Platforms Used: The total number of Social Media platforms used in the last 6 months.

Please use this information and the data in the excel spreadsheet "Usagef.xlsx" to answer the following questions:
