Expected ValueObjectivesVocabularyOf all workers at a certain factory, the proportions earning certain hourly wages are as follows:Suppose you are taking a multiple-choice test where each questions has choices a through e. If you get the answer correct, you get 4 points. If you get a wrong answer, you lose 1 point.Slide 6Slide 7Slide 8Expected ValueObjectives•Determine the expected value of an event.Vocabulary•expected value •decision theoryOf all workers at a certain factory, the proportions earning certain hourly wages are as follows: Find the expected hourly wage that a worker at this factory makes. hourly wage$8.50 $9.00 $9.50 $10.00$12.50$15.00proportion20% 15% 25% 20% 15% 5%Suppose you are taking a multiple-choice test where each questions has choices a through e.

If you get a wrong answer, you lose 1 point. Find the expected value of eliminating one answer and guessing among the remaining 4 possible answers.Suppose you are taking a multiple-choice test where each questions has choices a through e. If you get the answer correct, you get 4 points. If you get a wrong answer, you lose 1 point. Find the expected value of eliminating two answers and guessing among the remaining 3 possible answers.Suppose you are taking a multiple-choice test where each questions has choices a through e. If you get the answer correct, you get 4 points. If you get a wrong answer, you lose 1 point. Use decision theory and your previous answers to create a guessing strategy for this multiple-choice
