2 . Researchers want to determine how the height of a mountain can help explain the temperature at the top of the mountain . The two variables were measured for a sample ofmountains and the least squares regression line was calculated . It was also reported that18% of the variation in temperature at the top of a mountain can be explained by itsJainIfregression on the mountain's height . What is the value of the correlation between theJULIweektwo variables ?( A ) 0. 76( B ) 0.58( C ) - 0.34( D ) - 0.76( E ) - 0.58
