Some help please ? Social media and your grades - A college student wants to find out whether there is a relationship between time spent in minutes on social media platforms per day throughout the semester and the end of term percentagegrade. The student collects a random sample of 40 students and records the time spent in minutes and the end of term percentage grades. Minutes spent on social media per day (Minutes) is the X variable and End of termpercentage grade (Grades) is the Y variable in this scenario.A scatter plot of the data and the computer output from using statistical software to construct a linear model are shown below.Social Media Time and Grades5060708090100110Minutes spent on social media per dayCoefficientsEstimate Std.
