The dependent variable is the final grade, the first independent variable (x1x1) is the number of hours unsupervised each night, and the second independent variable (x2x2) is the number of hours of video games each night.   Coefficients Standard Error t-Stat p-value Intercept 57.968435 7.227955 8.020032 0.000201 Hours Unsupervised 5.131630 1.314283 3.904510 0.007943 Hours Playing Video Games 1.067855 1.615039 0.661194 0.533040     Indicate if any of the independent variables could be eliminated at the

A recent study examined the drinking behaviors of undergraduate college students (male and female freshmen). Each participant was asked how many alcoholic beverages they consumed during the past 7 days. The researchers wish to determine if there is a difference in the drinking habits of males and females in this age group.

In a 4 point grade system, an A is worth 4 points, a B is worth 3 points, a C is worth 2 points and a D is worth 1 point.  No points are awarded for an F.  Last semester Tanya received a B in a 4 credit hour course, an A in a three credit hour course, a C in a three credit hour course, and an A in another three credit hour course.  Grade point average (GPA) is calculated as a weighted average using the credit hours as weights and the number of points corresponding to the grades as pieces of data.  Calculate Tanya's GPA for the previous semester.  Round your answer to the nearest hundredth and explain in complete sentences your process.  Show all work.
