1. I read that 45% of the students have cheated at least once by not working on their homework assignments without illegal help. I don't believe that claim and randomly sample 100 students and subject them to a lie detector test. I find that 39% of them cheated with their homework at some point.
   1. State the H₀ and the H₁
   2. Test my hypothesis at the 99%, 95% and 90% confidence level.
