I. INDEPENDENT SAMPLE T-TEST
Problem 1: 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 given a life satisfaction test (known to have
high reliability and validity). Scores on the measuring range from 0 to 60 with high scores indicative
of high life satisfaction; low scores indicative of low life satisfaction. Calculate if there is a
significant difference between older and younger adults on perceived life satisfaction. Use alpha at
0.05.
