the hypothesis to test the slope of a regression equation is h0 ? = 0 (T/F)

The strength of the correlation between two variables depends on the sign of the coefficient of correlation. (T/F)

The coefficient of determination is the square root of the coefficient of correlation. (T/F)

Solution

False

The strength of the correlation between two variables depends on the sign of the coefficient of correlation. (T/F)
True

The coefficient of determination is the square root of the coefficient of correlation. (T/F)
False, It is the square of correlation coeffccient
