Does meditation improve the amount of sleep per night (in minutes) for teenagers aged 13-15 years? Two groups of teenagers aged 13-15 years were randomly selected. Group 1 consisted of thirty (30) teenagers aged 13-15 years who were instructed to follow a meditation program. Group 2 consisted of 20 teenagers aged 13-15 years who didn't follow any meditation program. The amount of sleep was recorded for both groups (meditation and non-meditation group) for a one-month period.

What descriptive and inferential statistics would you use to explore the relationship between these two variables? Why?
