For greenwood
= 2655.2222, s1^2 = 37929
For Pinewood
= 2836.3333, s2^2 = 182147
c) The test statistic tcalc = ()/sqrt(s1^2/n1 + s2^2/n2)
= (2655.2222 - 2836.3333)/sqrt(37929/9 + 182147/9)
= -1.158
d) df = (s1^2/n1 + s2^2/n2)^2/((s1^2/n1)^2/(n1 - 1) + (s2^2/n2)^2/(n2 - 1))
= (37929/9 + 182147/9)^2/((37929/9)^2/8 + (182147/9)^2/8)
= 11
P-value = 2 * P(T < -1.158)
= 2 * 0.1357
= 0.2714
