10) Which of the following statements is always true?
a). Half of the data is at or above the median value and half of the data is at or below the median value.
b). The median is halfway between the lowest value and the highest value.
c). The median value is halfway between the 1st and 3rd quartile marks.
Option C is correct answer because median is the value which divides the whole data set in to two equal parts.

Which of the following is NOT true about the bottleneck? The bottle neck is always the resource with the highest implied utilization The bottleneck is always the resource with the highest utilization The bottleneck is always the resource with the lowest capacity None of the above
2. Are the following statements true or false and explain why? (a) The median must always be a value in your data set. F but why (b) If given PXi and n, we can find the standard deviation of X. F but why (c) The standard deviation of X must always be positive F but why
Which statements are INCORRECT?If two data sets have the same standard deviation, they must have the same coefficient of variation.The number of standard deviations between the 25th percentile and the median is always the same as between the median and the 75th percentile.The range is considered the weakest measure of variability.The 5-number summary consists of the smallest observation, the first quartile, the median, the third quartile, and the largest observation.
