Part II. Student’s t-Test 2. A research study was conducted to examine the differences between older and younger adults on perceived life satisfaction. A pilot study was conducted to examine this hypothesis. Ten older adults (over the age of 70) and younger adults (between 20 and 30) were given a life satisfaction test. Scores on the measure range from 0-60 with high scores indicative of high life satisfaction.

4. A research study was conducted to examine the differences
between older and younger adults on perceived life satisfaction. A
pilot study was conducted to examine this hypothesis. Ten older
adults (over the age of 70) and ten younger adults (between 20 and
30) were give a life satisfaction test (known to have high

A research study was conducted to examine the impact of
eating a high protein breakfast on adolescents' performance during
a physical education physical fitness test. The students were
randomly selected and half received a high protein breakfast and
half a low protein breakfast. All of the adolescents, both male and
female, were given a fitness test with high scores representing
better performance. Test scores are recorded below.

A research study was conducted to examine the clinical efficacy
of a new antidepressant. Depressed patients were randomly assigned
to one of three groups: a placebo group, a group that received a
low dose of the drug, and a group that received a moderate dose of
the drug. After four weeks of treatment, the patients completed the
Beck Depression Inventory. The higher the score, the more depressed
