Explanation / Answer

1) The correct null hypothesis is B.

Treatment 1

N1: 5
df1 = N - 1 = 5 - 1 = 4
M1: 8.4
SS1: 107.2
s21 = SS1/(N - 1) = 107.2/(5-1) = 26.8


Treatment 2

N2: 5
df2 = N - 1 = 5 - 1 = 4
M2: 6.8
SS2: 54.8
s22 = SS2/(N - 1) = 54.8/(5-1) = 13.7


T-value Calculation

s2p = ((df1/(df1 + df2)) * s21) + ((df2/(df2 + df2)) * s22) = ((4/8) * 26.8) + ((4/8) * 13.7) = 20.25

s2M1 = s2p/N1 = 20.25/5 = 4.05
s2M2 = s2p/N2 = 20.25/5 = 4.05

t = (M1 - M2)/(s2M1 + s2M2) = 1.6/8.1 = 0.56

The t-value is 0.56218.

The p-value is .294696

. d) The result is not significant at p < .05. Faill to reject Ho . There is not sufficient evidence that difference is grater than 0
