In a hearing test, subjects estimate the loudness (in decibels)
of a sound, and the results are (mean = 70): 68, 67, 70, 71, 68,
75, 68, 62, 80, 73, 68.
What is the range?
22.40
324
6.76
18
4.73
Solution:
option D. 18
Explanation:-
The range is the difference between the highest and lowest values in the data set.
Ordering the data from least to greatest, we get:
62 67 68 68 68 68 70 71 73 75 80
The lowest value is 62.
The highest value is 80.
The range = 80 - 62 = 18.
=>
The mode of the data set is 68.
Explanation
The mode of a set of data is the value in the set that occurs most often.
Ordering the data from least to greatest, we get:
62 67 68 68 68 68. 70 71 73 75 80
We see that the mode is 68 .
