All the best. Name Email 1. which of the following is a correct statement? Probabilities are always whole numbers An event that is certain not to happen has a probability of 1.0 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 1.02. 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 continuous random variable discrete random variable3. The mean is a measure of symmetry position skewness variability central tendency4. If two events (both with probability greater than 0) are mutually exclusive, then They must be independent and complement They must be independent and could be complement They cannot be independent and could be complement They cannot be independent and they cannot be complement5. If you are told a sample has a mean of 19 and a variance of 0, what must you conclude? None of the above Someone has made a mistake. There is only one element in the sample There are no elements in the sample All the elements in the sample are 256. Consider the following data: 1, 7, 3, 3, 6, 4 the mean and median for this data are 4 and 3 1/3 4 and 3 4.8 and 3 4.8 and 3 1/2 4 and 3 1/2 7. Which of the following is not a property of a binomial experiment? the trials are independent the probabilities of the two outcomes can change from one trial to the next each outcome can be referred to as a success or a failure the experiment consists of a sequence of n identical trials8. 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 6/23 4/23 7/23 5/239. A frequency distribution provides the following information 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. The value of the measurement and the percent of individuals with that value10.
