Given Information:
A researcher would like to determine the effect of music on the level of relaxation.
Sample size (n) = 3
Significance level
State the hypothesis as follows:
Null Hypothesis i.e., there is no effect of music on the level of relaxation. In other words, mean difference in scores in relaxation before and after taking the test is 0.
Alternative Hypothesis: i.e., there is an effect of music on the level of relaxation.
