accompanying data on average anterior maximum inclination angle (AMIA) both in the clockwise direction and in the counterclockwise direction.

Round your answer to three decimal places.) (b) Assuming bivariate normality (normal probability plots of the Cl and Co samples are reasonably straight), carry out a test at significance level 0.01 to decide whether there is a linear association between the two variables in the population (as do the authors of the cited paper). State the appropriate null and alternative hypotheses. OH₂: P = 0 H₂: P<0 OH₁: P = 0 H₂: p > 0 O Ho: P = 0 H₂: P = 0 ⒸH₁: P = 0 H₂: p=0 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = P-value =
