You are interested in analyzing whether the use of apps like Vine and TikTok affect people's attention span. You are interested in estimating the following simple linear regression model: attention_span = Bo + B1use_apps + u where use_apps is an indicator variable equal to 1 if the individual uses the apps and zero otherwise. Attention_span is a variable summarizing the individual's attention span, measured in minutes. You collect information from a random sample of individuals and find that the average attention span for individuals who do not use these apps is 13.6 minutes while the attention span of individuals who do use the apps is 8.5 minutes. If you use OLS and these data to estimate the simple linear regression model shown above, what would be the value of Bo? Hint: remember, what is the interpretation of the intercept in a SLR?
