Answer #1

Null Hypothesis: Rho 0 or there is no correlation between hairlength and age. Question 21: obs9.63, p <0.001 Question 22: There is a sig negative relationship between age and hairlength. As age increases, hairlength decreasesQuestion 23: y=-2.759x+56.214 =- 2.759(16) +56.214 -41.264 + 56.214 -12.07 e12 About 12 inches. Question 24 The coefficient of determination is 0.86. Question 25: For every increase in age by one year, hairlength decreases by 2.76 inches Question 26: There is a medium effect of the DV on the IV
