1) It is easier to read the data values on a 3D column chart than on a 2D column chart. 1) 2) The midrange is not greatly affected by outliers. 2) 3) A trimmed mean may be preferable to a mean when a data set has extreme values. 3) 4) The sum of the probabilities of all compound events in a sample space equals one. 4) MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 5) The position of the median is: A) (n 1)/2 in any sample. B) n/2 if n is odd. C) n/2 in any sample. D) n/2 if n is even. 5) 6) If samples are from a normal distribution with = 100 and = 10, we expect: A) about 68 percent of the data within 90 to 110. B) about 95 percent of the data within 70 to 130. C) almost all the data within 80 to 120. D) about half the data to exceed 75. 6) 7) The Excel formula for the standard deviation of a sample array named Data is: A) =STDEV.S(Data). B) =STDEV.P(Data). C) =SUM(Data)/(COUNT(Data)-1). D) =STANDEV(Data). 7) 8) Which is true of skewness
