Q:

The graph below plots the values of y for different values of x:Plot the ordered pairs 1, 8 and 2, 3 and 3, 0 and 4, 1 and 5, 2 and 6, 1What is the correlation coefficient for the data plotted? βˆ’0.9 βˆ’0.6 0.6 0.9

Accepted Solution

A:
Answer:-0.6Step-by-step explanation:we know that The correlation coefficient is a measure of the strength of the straight-line or linear relationship between two variables. Correlation coefficients are expressed as values between +1 and -1we have(1,8),(2,3),(3,0),(4,1),(5,2),(6,1)using a Excel tool (CORREL function)see the attached tableThe correlation coefficient is -0.68
