A researcher would like to determine the relationship between drought length (lack of rain) and the size of a forest fire (fire intensity). It was found that as number of days without rain increased the risk of fire intensity also increased. The two variables were measured on a number of locations in California and a least squares regression line was calculated. It was report that 74% of the variation of fire intensity was explained by its regression on draught length. What is the value of the correlation between these two variables.
elect one:
a. -0.46
b. 0.82
c. 0.42
d. -0.82
e. 0.86
We have given,
Coefficient of determination
Therefore, Correlation coefficient
Positve relationship between two variable
