melisa1 [442]

Answer:

The test statistic  | t |  =4.45

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the first sample size n₁ = 36

Given that the second sample size n₂ = 34

Mean of the first sample x₁⁻ = 68.5

Mean of the second sample x₂⁻ = 70

<u><em>Step(ii):-</em></u>

Test statistic

       t = \frac{x^{-} _{1}-x^{-} _{2}  }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} }  } )}

     t = \frac{68.5-70}{\sqrt{2(\frac{1}{36}+\frac{1}{34} ) } }

    t = \frac{-1.5}{0.337} = -4.45

The test statistic  | t | = |-4.45| =4.45
