Solution:
Given:
A test consists of 740 true false questions. Thus n = 740
A student guesses on each answer.
Hence p = probability of correct answer = 0.5 and q = probability of incorrect answer = 0.5
We have to find standard deviation of number of correct answers.
It is given by:
Thus correct answer is :C . 13.60

A test consists of 10 true/false questions. To pass the test a student must answer at least 6 questions correctly. If a student guesses on each question, what is the probability that the student will pass the test? Round to three decimal places. A. 0.377 B. 0.828 C. 0.205 D. 0.172
A test consists of 10 true or false questions. To pass the test a student must answer at least eight questions correctly. If the student guesses on each question what is the probability that the student will pass the test
A test consists of 10 true/false questions. To pass the test a student must answer at least 6 questions correctly. If a student guesses on each question, what is the probability that: a. the student will pass the test b. the student will fail the test c. the student will get a 100 (all questions will be answered correctly)
A student takes a true-false test consisting of 15 questions. Assume that the student guesses at each question and find the probability that a. the student gets at least one question correct. b. the student gets a 80 % or better on the exam.
A student takes a true-false test that has 14 questions and guesses randomly at each answer. Let X be the number or questions answered correctly. Find P(6). A)0.1222 B)0.2095 C)0.0001 D)0.183
a student takes a true false test that has 13 questions and guesses randomlyat each answer. let x be the number of questions answered correctly. find (p fewer than 4
A test consists of 25 multiple choice questions. Each question has 5 possible answers, or which only one is correct. If a student guesses on each question, find the following. a) The probability that he will guess all of them correct b)The probability that he will guess at most 15 correct. c)The probability that he will guess at least one correct. d) The mean and the standard deviation of the number of correct answers. e)Estimate the probability of the number...
