Statistics 2 Task1: A) Scatter plot: n=7 Test statistic,t = -0.879 a=0.05 critical value = t(a/2, n-2) = t(0.025,5) = 2.571 B) H0: population correlation coefficient = 0 H1: population correlation coefficient not equal to 0 (there is a linear correlation between the proportion of wins and the above difference) Since |t|<2.571 hence H0 cannot be rejected so there is NO sufficient evidence to
