Q. Look at this set of 66 numbers:\newline93,81,83,83,43,2293, 81, 83, 83, 43, 22\newlineHow would the median change if the number 2424 replaced one of the 8383's in the set?\newlineChoices:\newline(A)increase\newline(B)decrease\newline(C)no change\newline
  1. Identify and Arrange Original Set: Identify the original set and arrange it in ascending order.\newlineOriginal set: 93,81,83,83,43,2293, 81, 83, 83, 43, 22\newlineSorted set: 22,43,81,83,83,9322, 43, 81, 83, 83, 93
  2. Calculate Median of Original Set: Calculate the median of the original set.\newlineSince there are 66 numbers, the median is the average of the 33rd and 44th numbers.\newlineMedian = (81+83)/2=82(81 + 83) / 2 = 82
  3. Replace and Sort New Set: Replace one of the 8383's with 2424 and sort the new set.\newlineNew set: 9393, 8181, 2424, 8383, 4343, 2222\newlineSorted new set: 2222, 2424, 4343, 8181, 8383, 9393
  4. Calculate Median of New Set: Calculate the median of the new set. Median = (43+81)/2=62(43 + 81) / 2 = 62
