A mental health agency measured the self‐esteem score for randomly selected individuals with disabilities who were involved in some work activity within the past year. The Excel file Self Esteem provides the data, including the individuals’ marital status, length of work, type of support received (direct support includes job‐related services such as job coaching and counseling), education, and age.
a. Apply ANOVA to determine if self‐esteem is the same for all marital status levels. If the null hypothesis is rejected, apply the Tukey–Kramer multiple comparison procedure to identify significant differences.
b. Use the chi‐square test to determine if marital status is independent of support level.
