we use instead of and n instead of NB. We divide the sum of the observations by n1 instead of nC. The observations are ranked and select the middle value for the population meanD. There are no differences126. Which of the following measures of central location is affected most by extreme values?A. MedianB. MeanC. ModeD. Geometric mean127. In which of the following distributions is the probability of a success usually small?A. BinomialB. PoissonC. HypergeometricD. All distribution128. Which of the following is not a requirement of a probability distribution?A. Equally likely probability of a successB. Sum of the possible outcomes is 1.00C. The outcomes are mutually exclusiveD. The probability of each outcome is between 0 and 1129 For a binomial distributionA. n must assume a number between 1 and 20 or 25B. p must be a multiple of .10C. There must be at least 3 possible outcomesD. None of the above130. Events are independent if A. By virtue of one event happening another cannot. B. The probability of their occurrence is greater than 1. C. We can count the possible outcomes. D. The probability of one event happening does not affect the probability of another event happening. E. None of the above.131 . The Special Rule of Addition is used to combine A. Independent events. B. Mutually exclusive events C. Events that total more than one. D. Events based on subjective probabilities E. Found by using joint probabilities.132. We use the General Rule of Multiplication to combine A. Events that is not independent. B. Mutually exclusive events. C. Events that total more than 1.00. D. Events based on subjective probabilities E. Found by using joint probabilities.133 A nominal scale variable is A. Cannot have more than two categories. B. Has a meaningful zero point. C. Usually the result of counting somethingD. May assume negative values.134. We wish to develop a confidence interval for the population mean. The shape of the population is not known
