All the best. Name Email 1. An experiment consists of making 80 telephone calls in order to sell a particular insurance policy. The random variable in this experiment is a complex random variable simplex random variable discrete random variable continuous random variable2. If two events (both with probability greater than 0) are mutually exclusive, then They cannot be independent and could be complement They must be independent and could be complement They cannot be independent and they cannot be complement They must be independent and complement3. A frequency distribution provides the following information The value of the measurement and the percent of individuals with that value The value of the measurement and the percent of individuals with that value or a smaller one The value of the measurement and the number of individuals with that value.4. The probabilities of X, Y, Z becoming managers are 4/9, 2/9 and 1/3 respectively. The probability that the bonus scheme will be introduced, if X, Y , Z becomes managers are, 3/10, 1/2, and 4/5 respectively. If the bonus scheme has been introduced, what is the prob. that a manager appointed was X 7/23 5/23 6/23 4/235. which of the following is a correct statement? Probabilities are numbers whose values can be from -1 to +1 The total of all the probabilities assigned to all outcomes in a sample space must be equal to 1.0 Probabilities are always whole numbers An event that is certain not to happen has a probability of 1.06. Consider the following data: 1, 7, 3, 3, 6, 4 the mean and median for this data are 4.8 and 3 1/2 4 and 3 1/3 4.8 and 3 4 and 3 1/2 4 and 37.

The mean is a measure of variability position central tendency skewness symmetry9. If you are told a sample has a mean of 19 and a variance of 0, what must you conclude? Someone has made a mistake. There is only one element in the sample All the elements in the sample are 25 None of the above There are no elements in the sample10. Which of the following is not a property of a binomial experiment? each outcome can be referred to as a success or a failure the trials are independent the experiment consists of a sequence of n identical trials the probabilities of the two outcomes can change from one trial to the nextThank you for taking - Managerial Statistics Poisson and Bayes theorem Give your best to show up in the board below: [mlw_quizmaster_leaderboard mlw_quiz=7] Share this:FacebookTwitterEmailGoogleLinkedIn
