When taking multiple choice test with 4 options for answers, there is a 25% chance that you will get the question right just by random guess. You wish to determine how many correct answers you can get just by random guessing on a 100 question multiple choice test.
np>10np>10, At least 10 expected successes.
n(1−p)>10n(1−p)>10, At least 10 expected failures.
Approximate with N(np,np(1−p))
Binomial Distribution
None of the above.
Normal Population Distribution
Uniform Distribution
From the given information,
The required correct answer is,
np>10, At least 10 expected successes.
n(1−p)>10, At least 10 expected failures.
Hence,
Approximate with N(np,np(1−p)).
Thank you.

You are taking a 18 question multiple choice test, where each question has 5 possible answers. Identify n and p. Write p as a fraction. n = p = Find the mean and standard deviation of the binomial random variable. Write your answers as a fraction, expression or decimal with at least 4 decimal places. M = = What would be an unusually high number of correct questions? Give your answer in the box above as a whole number. or...
When taking a 11 question multiple choice test, where each question has 4 possible answers, it would be unusual to get or more questions correct by guessing alone. Give your answer in the box above as a whole number.
Q. 27 A multiple choice test consists of 25 questions with possible answers a, b, c, d, and e. Estimate the probability that with a random guessing, the number of correct answers is at least 10.
just answer nuber 18 please Discrete Binomial Distributions: Assume that you are taking a multiple choice test that you have not studied for! The test only has 9 questions and each question has four possible answers. You plan to randomly guess on all 9 questions and the probability you get one correct is the same for all questions. 17. What is the probability you get the first question correct? A. 0.25 B. 0.50 C. 0.75 D. 1.00 18. Using the...

This is attempt 1 of 3. When taking a 10 question multiple choice test, where each question has 3 possible answers, it or more questions correct by guessing alone. would be unusual to get Give your answer in the box above as a...
3. You are taking a multiple-choice quiz that consists of 6 questions. Each question has four possible answers, only one of which is correct. To complete the quiz, you randomly guess the answer to each question. a) Find the chance of guessing exactly three answers correctly b) Find the chance of guessing more than four answers correctly
According to a poll of adults about 42% work during their summer vacation. Suppose that this claim about the population proportion is true. Now if we take a sample of 75 adults, and find the sample proportion p̂ p^ of adults who work during summer vacation. 1. What is the expected value of sample proportion p̂ p^? 2. What is the standard deviation of sample proportion p̂ p^? 3. The shape of the sampling distribution of sample proportion p̂ p^...
Suppose you forget to study for an exam. The exam is multiple choice and has one correct answer of 4 possible choices. Suppose that the exam contains 20 questions of which you guess on every one. a. What is the probability that you get exactly 10 questions correct by guessing? b. What is the probability that you get at most 1 question correct by guessing? c. What is the probability that you get at least 1 question correct by guessing?...
(1 point) A multiple-choice test consists of 22 questions with possible answers of a, b, c, d. Estimate the probability that with random guessing, the number of correct answers is at least 12. The answer above is NOT correct. (1 point) A multiple-choice test consists of 22 questions with possible answers of a, b, c, d. Estimate the probability that with random guessing, the number of correct answers is at least 12. 0.0029
HW4.5. Multiple-choice Test A multiple-choice test has 43 questions. Each question has 4 choices. If you guess at random on all the questions and each guess is independent from one another, what are the expected value and standard deviation of the number of correct answers on your test? 1. What is the expected value of the number of correct answers on your test? (a) 10.75 (b) 21.5 (c) 8.75 (d) 11.75 2. What is standard deviation of the number of...
