From the sample data, it is found that the corresponding sample means are:
Also, the provided sample standard deviations are:
and the sample size is n = 10. For the score differences we have
(3) Test Statistics
The t-statistic is computed as shown in the following formula:
(4) The decision about the null hypothesis
Since it is observed that it is then concluded that the null hypothesis is not rejected.
Using the P-value approach: The p-value is p = 0.24552, and since it is concluded that the null hypothesis is not rejected.
(5) Conclusion
It is concluded that the null hypothesis Ho is not rejected. Therefore, there is not enough evidence to claim that the population mean μ1 is different than μ2, at the 0.01 significance level.
