Question: Let us explore whether exercise impacts sleep duration (DV - interval data, measured in minutes). We argue that sleep pattern is improved by regular exercise (IV - dichotomous, exercise versus no exercise) through a reduction in stress and physical fatigue. We expect to reject the null hypothesis, meaning an average sleep duration difference exists between the exercise and non-exercise groups. We anticipate the exercise group will have a higher sleep duration due to the theorized benefits.

Independent Samples t-test: Sleep Duration by Exercise Group, t(df=38) = 2.34, p = 0.024

The T-test statistic (2.34) appears significant enough to differentiate sleep duration between exercise and non-exercise groups. Observing the p-value (0.024) being statistically significant, the null hypothesis can be rejected. That supports our expectation: individuals who exercise regularly tend to sleep longer on average.
