This is the result of a matched pairs t test, to test if childrens maths scores have decreased.
P-value is 1, does this mean that there is absolutely no change in scores, or just that the hypothesis that μ is equal to 0 cannot be rejected.
I'm so confused, what would you conclude?
Hypothesis test results:
μ : mean of Variable
Ho : μ = 0
Ha : μ < 0
Sample Mean: 6.78
Std. Err: 0.9084986
