Performing Hypothesis Tests: Proportions: Videos & Practice Problems

A research team surveys $100$ employees and asks each, “How do you feel about your current stress level compared to your colleagues?” The responses are:

• $47$ employees said “more stressed”  
• $35$ employees said “less stressed”
• $18$ employees said “about the same.”

Using the sign test, examine the null hypothesis that the proportion of employees who feel more stressed equals the proportion who feel less stressed. Use $\alpha =0.05$.
