A linear regression equation is computed for a sample of n = 13 pairs of X and Y scores. For the analysis of regression testing the significance of the equation, what are the df values for the Fratio? df = 1, 11 df = 1, 12 df = 2, 10 df = 2, 11 A researcher finds a significant correlation between the amount of time spent watching television and blood pressure for a sample of 40-year-old men.

If the researcher tests the significance of the correlation, what value will be obtained for the t statistic? 0.6/0.16 = 3.75 0.6/0.4 = 1.50 0/6/0.8 = 0.77 0.6/1.0 = 0.6 A set of X and Y scores has a regression equation with a slope of b = 4.
