Asperger Asperger SolutionSet Up Hypothesis Null Hypothesis

Solution

Set Up Hypothesis
Null Hypothesis ,there Is No-Significance between them Ho: u1 = u2
Alternate Hypothesis , there Is Significance between them H1: u1 != u2
Test Statistic
X(Mean)=-0.001
Standard Deviation(s.d1)=0.15
Number(n1)=19
Y(Mean)=0.42
Standard Deviation(s.d2)=0.17
Number(n2)=17
we use Test Statistic (Z) = (X-Y)/Sqrt(s.d1^2/n1)+(s.d2^2/n2)
Zo=-0.001-0.42/Sqrt((0.0225/19)+(0.0289/17))
Zo =-7.84
| Zo | =7.84
Critical Value
The Value of |Z ?| at LOS 0.05% is 1.96
We got |Zo | =7.839 & | Z ? | =1.96
Make Decision
Hence Value of | Zo | > | Z ?| and Here we Reject Ho
P-Value: Two Tailed ( double the one tail ) - Ha : ( P != -7.84 ) = 0
Hence Value of P0.05 > 0,Here we Reject Ho

A. There is strong evidence that the mean score for Asperger syndrome population
is different than that of the non-Asperger population.
