Answer 1

Give me the regression equation and the results of the statistical test (including null hypothesis tested and the decision reached) for this data (include null and decision) Want to predict the number of dog bites from self-esteem, shoe, extraversion, and 40 yd.Include SPSS

The estimated regression line is

Dog Bites = 4.424 -0.419*Self-Esteem +0.423*Shoe +0.058*Extraversion+0.485*40yd

Ho: The regression model is not significant.

H1: The regression model is significant.

Calculated F= 14.496, P=0.001 which is < 0.05 level of significance. Ho is rejected. The regression model is significant.
