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)=762.875
Standard Deviation(s.d1)=199.79431 ; Number(n1)=24
Y(Mean)=759.125
Standard Deviation(s.d2)=212.8364; Number(n2)=24
we use Test Statistic (t) = (X-Y)/Sqrt(s.d1^2/n1)+(s.d2^2/n2)
to =762.875-759.125/Sqrt((39917.76631/24)+(45299.33316/24))
to =0.062929
| to | =0.0629
Critical Value
The Value of |t | with Min (n1-1, n2-1) i.e 23 d.f is 1.714
We got |to| = 0.0629293 & | t | = 1.714
Make Decision
Hence Value of |to | < | t | and Here we Do not Reject Ho
P-Value:Left Tail - Ha : ( P < 0.062929 ) = 0.52482
Hence Value of P0.05 < 0.52482,Here We Do not Reject Ho

to =0.0629
Failed to reject tha cliam, Uw is equal to Ut because the test statistic is less than crtical point
