Increased social media usage is being linked to fewer interpersonal relations and increased loneliness across today’s younger generation. On average, millennials spend 6 hours per week on social media. Connect-U is a new business which attempts to connect people via social media while also encouraging in-person interactions. Connect-U is hoping to decrease the effects of social media usage on loneliness by decreasing total time spent using social media per week. After 6 months of operations, the average time a sample of 100 customers spent using social media per week was 5.75 hours. Historical records indicate that the standard deviation for weekly social media usage is 1 hour. You would like to perform a test to determine whether Connect-U is successful at its mission. What is the actual value of the test statistic?
