Question

Provide a written description of the complement of the given event: "At least one of the phones is None of the phones are bad. At least one of the phones is good. None of the phones are good. All of the phones are bad. At least two of the phones are bad. True or false: The data given in the following table satisfies all of the required conditions for a probability distribution. True False, because Sigma P(x) notequalto 1. False, because there is a negative value for x. False, because there is a missing value of x = -1. Consider the following probability distribution. The mean or expected value is: 0.08 1.0 1.5 3.0 None of these. Consider the following probability distribution. The variance is: 0.0 1.18 2.65 3.05 None of these. Which of the following is not a characteristic of a binomial experiment? A fixed number of trials. The of success is the same for each trial. The outcome of each trial is independent of the outcome of any other trial. The probability of success always equals the probability of failure. None these. If a procedure yields a binomial distribution with n = 1000 trials and probability of success p = 0.65, then use mu plusminus 2 sigma to find the range of usual values. 620 to 680 195 to 1105 423 to 877 635 to 665 469 to 531

Explanation / Answer

40)

HENCE option C

41)

Variance=E(X2)-(E(X))2 =4.9-1.52 =2.65

43)

here mean =np=1000*0.65=650

std deviation =(np(1-p))1/2 =15.08

hence mean-/+2*std deviaiton =620 to 680

option A is correct

X p(X) Xp(X) -2 0.1 -0.2 0 0.2 0 1 0.1 0.1 2 0.2 0.4 3 0.4 1.2 TOTAL 1.5
