1) What is the value of the correlation coefficient? (CAREFUL:EXCEL'S REGRESSION FUNCTION WILL NOT LET YOU KNOW WHETHER OR NOT THIS VALUE IS NEGATIVE)(ANSWER TO 2 DECIMAL PLACES)

2) What is the value of the coefficient of determination?(ANSWER TO 2 DECIMAL PLACES)

3) State the estimated regression equation.(ANSWER ONLY THE VALUE AFTER THE EQUAL SIGN WITH VARIABLES TO 0 DECIMAL PLACES. FOR EXAMPLE IF THE EQUATION IS: y = 12,345.67x + 98,765.43...YOUR ANSWER IS: 12,346x + 98,765)
