Complete the parts below. a) Draw a scatter diagram of the? data, treating height as the explanatory variable and weight as the response variable b) ?Determine the? least-squares regression line. Test whether there is a linear relation between height and weight at the ? = 0.05 level of significance. Determine the? least-squares regression line. c) Test whether there is a linear relation between height and weight at the ?=0.05 level of significance. State the null and alternative hypotheses. Determine the? P-value for this hypothesis test. State the appropriate conclusion at the ?=0.05 level of significance. d) Remove the values listed for Player 4 from the data table. Test whether there is a linear relation between height and weight. Determine the? P-value for this hypothesis test. State the appropriate conclusion at the ?=0.05 level of significance. Do you think that Player 4 is? influential?
