Can someone thoroughly explain a to f? Thanks

1. Dr. Alleyne collected data on the number of absences from tutorials (X) and a student's score on the Stats final exam (Y). A sample of 6 students yielded the following information: Number of absences (X) Score (Y) 95 86 6 70 9 60 20 2 92 a. Calculate the correlation coefficient. b. Develop the estimated simple regression equation, that is, provide the values of a and b for the equation ? = a + bX . C. Interpret the intercept and the slope of the regression. d. Predict a student's score in stats if they were absent for 7 tutorials e. Given your answer in part (a), what is the value of the coefficient of determination (that is r2) for the regression. f. Interpret the r calculated in part (e)
