Problem
To investigate whether children from divorced homes are more psychologically unhealthy, researchers obtained a Global Assessment of Functioning (GAF) score from n=75 individuals from divorced families. The sample's mean GAF score was 72.5 with a standard deviation of 6.7. If the population average for GAF scores is μ=79, is there enough evidence to conclude that individuals from divorced families are more psychologically unhealthy? Conduct a one-sample t-test with α=0.05, two-tailed test. Make sure to include all 4 steps. what is the take-home message from your results?
