To interpret the results, look at the p-value and the alpha value. If the p-value is less than the alpha value, the null hypothesis is rejected. If the p-value is greater than the alpha, the null hypothesis is accepted.

Write your results out on a research document like this: "It is not significant. M = 48.70, SD = 27.01461, t(9) = 5.701, p < .00, alpha = .05."

M: mean

SD: standard deviation

t(9): "t" means t-test; "(9)" is the degrees of freedom, which is 9 in this case

p: p-value

alpha: alpha value

Write this for each of the independent and dependent variables.
