Subject: need a paired difference statistical analysis

Details: I am writing a thesis and need a paired difference statistical analysis with a confidence level at 95% with t-value for alpha of 0.25

My hypothesis is that there is a statistically significant differnce between two test scores for

the following samples (pre and post tests)

1. 17 15

2. 27 24

3. 33 33

4. 31 30

5. 32 25

6. 32 21

7. 38 26

Is this the correct way to measure if an intervention was successful for seven samples?

(I gave a pre and post test)

#### Solution Preview

Ho: Âµ1 - Âµ2 = 0, or Md=0

<br>H1: Âµ1 - Âµ2 <> 0 or Md<>0

<br>where Md is the difference between sample means, Âµ1 - Âµ2 is the difference between population means specified by the null hypothesis (usually zero), and is the estimated standard error of the difference between means.
