Question

Question 3 of 8 When the two-sample t-test is carried out the researchers find that the test statisticist 2.83 and P-value = 0.003 P-value 0.003 tells us that it would be quite unlikely to get results like that observed in our study (or more extreme) assuming that: Sorbo r war t hassamentowie stats aug2018 33/m_inference for relations There is no difference in effectiveness between the two metros.

Method 2 is more effective than Method 1 for learning the motor skill There is a difference in effectiveness between the two methods. estion 4 of 8

Answer 1

Given test statistic t = 2.83 and p - value = 0.003

For a = 0.05

Decision rule : If p-value < 0.05 we reject the null hypothesis Ho otherwise we fail to reject the null hypothesis.

Our p-value = 0.003 < 0.05 we reject the null hypothesis

Conclusion : There is a difference in effectiveness between the two methods.
