10. The t test for two independent samples - One-tailed example using tables Most engaged couples expect or at least hope that they will have high levels of marital satisfaction. However, because 54% of first marriages end in divorce, social scientists have begun investigating influences on marital satisfaction. [Data source: This data was obtained from the National Center for Health Statistics.] Suppose a clinical psychologist sets out to look at the role of sexual orientation in relationship longevity. He decides...
