Sagot :
Answer:
r = 0.8
Step-by-step explanation:
The correlation coefficient, "r", represents the correlation between the independent and dependent variable. The closer "r" is to 1, the better the correlation. Likewise, if "r" is closer to 0, there will be hardly any correlation.
The coefficient of determination, R², is the proportion of the variation in the dependent variable that is predictable from the independent variable, or how well the data fits the regression model.
In this case, since R²=64%=0.64, then r=√(0.64)=0.8
This means that there is a strong correlation between age and height.
