Expert Answer :Probability Assignment Problems

Solved by verified expert :1-A math test consists of 17 multiple choice questions,each with five possible answers (a, b, c, d, e), only one of which is correct.Assume that a student takes the test and randomly answers the questions.Explain why this situtation describes a binomial experiment. Be specific.2-A math test consists of 17 multiple choice questions,each with five possible answers (a, b, c, d, e), only one of which is correct.Assume that a student takes the test and randomly answers the questions.What is the probability that the student will get no questions correct?Round your answer to three decimal places.3-A math test consists of 17 multiple choice questions,each with five possible answers (a, b, c, d, e), only one of which is correct.Assume that a student takes the test and randomly answers the questions.Would it be unusual for the student to get no questions correct? Explain.4-A math test consists of 17 multiple choice questions,each with five possible answers (a, b, c, d, e), only one of which is correct.Assume that a student takes the test and randomly answers the questions.What is the probability that the student gets at least one question correct?Round your answer to three decimal places.5-A math test consists of 17 multiple choice questions,each with five possible answers (a, b, c, d, e), only one of which is correct.Assume that a student takes the test and randomly answers the questions.What is the probability that the student gets exactly five questions correct?Round your answer to three decimal places.6-Use Table A-2 to answer the following questions. Do not round your answers.P(z<1.43) =P(z>-0.07) =P(-2.34 0.5c.p = 0.5d.p < 0.511-Suppose you are going to test the claim that more than half of adultsprefer a window seat when they fly.What is the null hypothesis?a.p > 0.5b.p is not equal to 0.5c.p < 0.5d.p = 0.512-Suppose you are going to test the claim that more than half of adultsprefer a window seat when they fly.What is the alternative hypothesis?a.p > 0.5b.p is less than or equal to 0.5c.p < 0.5d.p = 0.513-Suppose you are going to test the claim that more than half of adultsprefer a window seat when they fly.What kind of hypothesis test would you use to test the claim?a.right-tailedb.left-tailedc.skewed-tailedd.two-tailed14-Suppose you are going to test the claim that more than half of adultsprefer a window seat when they fly.The results of a poll indicated that 492 of 806 adults preferred awindow seat when they were flying.Calculate the test statistic for this hypothesis test.Round your answer to two decimal places.15-Suppose you are going to test the claim that more than half of adultsprefer a window seat when they fly with a significance level of 0.05.The results of a poll indicated that 492 of 806 adults prefered awindow seat when they were flying.What is your conclusion of the hypothesis test?What is your conclusion about the original claim?
