Suppose a teacher gives her statistics class a​ four-question, multiple-choice quiz at the beginning of the semester to measure how well prepared they were for the class. The accompanying table shows the number of students who had​ 0, 1,​ 2, 3 and 4 questions correct. Using α = 0.05, perform a​ chi-square test to determine if the number of correct answers per student follows the binomial probability distribution.

In a statistics class, Maya takes a multiple-choice quiz. There are 10 questions. Each question has five possible answers. Maya will pass the test if she studies so that she has a 75% chance of answering each question correctly. Let x be the number of of correct answers. (Round probabilities to 4 decimal places) a. Define the Random Variable, x ~ b. What is the PDF formula? c. Find the probability that Maya answers exactly 4 of the questions correctly?...

A quiz for a Psychology class consists of 5 questions. The questions are multiple-choice with 4 possible answers each, with only one correct answer. A student randomly guesses on all 5 questions. create a probability distribution for the number of correct answers what is the probability that the student will pass with a 60% or better what is the probability that the student will answer less than 4 correct

A student is taking a multiple-choice quiz in which each question has five possible answers, exactly one of which is correct. He knows 85% of the material being tested. Assume the teacher has chosen the questions independently and at random from among all the questions she could have chosen. When the student knows the correct answer to a given question, he has a 98% chance of marking it correctly. When he does not know the answer, he answers by marking...

A Student takes a multiple choice Quiz where there are "n" possible answers in each question. 1- The Student answers the question correctly if the Student knows the answer. 2- The Student answers the question randomly if the Student doesn't know the answer. 3- Suppose that the Quiz has 20 questions, and that the Student knows "80%" of the questions correctly. what is the expected number of questions that the Student will get correctly?

. A quiz has 25 multiple choice questions. Each question has 3 possible answers, one of which is correct. A correct answer is worth 4 points (a ticket with the value of 4), but a point is taken off for each incorrect answer (a ticket with the value of -1). A student answers all 25 questions by guessing at random. a) Present the problem with an appropriate box model. Find the expected value and the standard error for the sum...

A multiple choice quiz involves 30 questions, each with 5 alternative answers. Each question is awarded 10 marks if the correct answer is chosen, and 0 marks otherwise. Assume that one particular student answers the quiz by guessing, with a 1 in 5 chance of answering any single question correctly, independently of all other questions. Let X be the total number of marks obtained by this student. The mean and standard deviation of X are: Select one:

Richard has just been given a 8-question multiple-choice quiz in his history class. Each question has four answers, of which only one is correct. Since Richard has not attended class recently, he doesn't know any of the answers. Assuming that Richard guesses on all eight questions, find the indicated probabilities. (Round your answers to three decimal places.) (a) What is the probability that he will answer all questions correctly? (b) What is the probability that he will answer all questions...

Multiple Choice Test Chris is sitting a multiple choice test in statistics. The test consists of 9 items and each item has 5 options. After the test, Chris told you he didn’t study for the test at all and guessed all answers. If Chris guessed each and every item in the test, describe the probability distribution for the number of correct guesses. Present the probability distribution in the form of a table using 6 decimal points in your answers. (Use...
