Solve the problem.Ten students in a graduate program were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 and 4.0. The following data were obtained regarding their GPAs on entering the program versus their current GPAs. By using linear regression, the following function is obtained: 
where x is entering GPA and y is current GPA. Use this function to predict current GPA of a student whose entering GPA is 3.8. Round to the nearest hundredth. Entering GPA Current GPA 3.53.63.83.73.63.93.63.63.53.93.93.84.03.73.93.93.53.83.74.0
