Community college instructors' salaries in one state are very low, so low that educators in that state regularly complain about their compensation. The national mean is
\( \$ 51,851 \), but instructors from Mississippi claim that the mean in their state is significantly lower. They survey a simple random sample of 46 colleges in the state and
calculate a mean salary of \( \$ 48,923 \) with a standard deviation of \( \$ 15,489 \). Test the instructors' claim at the 0.025 level of significance.
Step 3 of 3: Draw a conclusion and interpret the decision.

Homework Origins and How Question Bank Helps
Who Invented Homework?
Homework dates back to the late 19th century, often being credited to an Italian educator named Roberto Nevilis as its creator. Nevilis introduced homework-like assignments as an extra means of reinforcing education outside school hours; although homework-type assignments existed prior to Nevilis. Indeed, ancient civilizations such as Greeks and Romans utilized similar strategies of reinforcing learning outside classroom hours. While Nevilis formalized this practice into homework as we know it today; its meaning has significantly evolved with different cultural and educational influences shaping its current meaning over time.
Does Homework Help Students Learn?
Yes, homework can be a useful tool for reinforcing what children learn in the classroom, but its efficacy is dependent on numerous things. According to research, homework that is purposeful and balanced can help students acquire crucial skills such as time management, critical thinking, and problem solving. However, excessive or badly designed schoolwork can cause stress and exhaustion. Homework works best when it is designed to reinforce key concepts, foster independent thinking, and provide opportunities for personal reflection. So, while homework can be beneficial, the trick is determining the appropriate amount and manner to help pupils learn without overwhelming them.
