Question

Use the given data find the equation of the regression line. Round the final values to three significant digits, if necessary. 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. Find the value of the linear correlation coefficient: A study was conducted to compare the average time spent in the lab each week versus course grade for computer programming students. The results are recorded in the table below.
