An analyst performs a random survey at an entertainment event. The analyst gathers the ages for each survey participant: 32, 16, 81, 17, 50, 93, 24, 10, 67, 42, 89, 15, 76, 29, 33, 55, 18, 37, 48, 82

The correct answer is A. 93 E. 10. 10 and 93 are the two values the analyst should use to determine the range. To calculate range, the minimum value should be subtracted from the maximum value. To determine the range in this data set, the analyst can perform the following calculation: The analyst should not use th

Explanation

10 and 93 are the two values the analyst should use to determine the range. To calculate range, the minimum value should be subtracted from the maximum value. To determine the range in this data set, the analyst can perform the following calculation: The analyst should not use the values 32, 82, 48, or 45. 32 and 82 are the first and last numbers in the unordered set. 48 is the average or mean, which can be calculated by summing the numbers and dividing by the number of values in the data set: 32 + 16 + 81 + 17 + 50 + 93 + 24 + 10 + 67 + 42 + 89 + 15 + 76 + 29 + 33 + 55 + 18 + 37 + 48 + The total number of numbers in the list is 20, so: Mean = Sum / Total Number of Numbers = 960 / 20 = 48 45 is the median. The median is the middle number in the sorted list. Since there are an even number of elements, the analyst must take the average of the two middle numbers: Median = (42 + 48) / 2 = 45
